option C) Pons
Pons, or better still, the pons Varolii is a band of nerve fibers located within the brain stem. While, the brain stem is known to connect the spinal cord(Hind brain) to the fore brain
Thus, Pons extends through the hindbrain, midbrain, and forebrain.
"the Reticular formation extends through the hindbrain, midbrain, and forebrain."
The brain is a complex organ. It acts as the control center of the body. There are three major divisions of the brain, the forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon).
The forebrain is by far the largest brain division. It includes the cerebrum, which counts for about two-thirds of the brain's mass and covers most other brain structures The forebrain has two major parts, the diencephalon and the telencephalon. The forebrain is responsible for functions related to thinking, perceiving, and evaluating sensory information.
The midbrain also called the mesencephalon connects the hindbrain and the forebrain. The midbrain serves important functions in motor movement, particularly eye movements and in auditory and visual processing. The midbrain regulates movement and aids in the processing of auditory and visual information.
The hindbrain is composed of two subregions called the metencephalon and myelencephalon. There are three main parts of hindbrain, such as pons, cerebellum, and medulla oblongata. The hindbrain assists the regulation of autonomic functions, maintaining balance and equilibrium, movement coordination, and the relay of sensory information.
The reticular formation is a set of interconnected nuclei which are located throughout the brainstem. Reticular formation extends through the hindbrain, midbrain, and forebrain.

The reticular formation extends through the hindbrain, midbrain, and forebrain
Brain consists of nerve tissues and which performs the function of sensory information integration and directing the motor response. Hind brain, mid brain and the forebrain are the three regions of the brain.
Reticular formation is a group of nuclei found throughout the brain stem which includes dorsal tegmental nuclei in the midbrain, central tegmental nuclei in the pons and central and inferior nuclei in the medulla. It is found predominantly in the midbrain but also it extends to the forebrain and the hindbrain. It controls the sleep/wake cycle, motor activity, alertness and arousal because it contains neurons which produce neurotransmitters like dopamine and serotonin.
The ventral tegmental area of the reticular formation is the largest dopamine producing area in the brain. The midbrain reticular formation contains the pedunculopontine nucleus and laterodorsal tegmental nucleuses which are the largest sites for acetylcholine production in the brain. The ascending reticular formation or reticular activating system is involved in sleep/wake cycle whereas the descending reticular formation is involved in motor movement.

The structure that is common to hindbrain, midbrain and forebrain is reticular formation.
The spinal cord and brain are two major parts of the central nervous system. Nerve cells that are soft and spongy make up the brain. The brain is divided into three major parts:
In the brain, brain stem, cerebrum, and cerebellum are also present. The link between the brain and spinal cord is made up of the brain stem. In the brain stem, reticular formation is present. It is nothing but a group nuclei present inside the brain stem. They are extending throughout the midbrain, hindbrain, and forebrain. It mainly plays a significant role in arousal and consciousness. The tegmentum of the brain stem contains a complex network of interconnected circuits of neurons, which is associated with the reticular formation.
