A codon is a sequence of three bases found on the messenger RNA (mRNA) molecule which is translated to produce an amino acid. Each amino acid is coded by one or more specific codons. If the codon is changed through a mutation, the amino acid produced may be different. However, in this case, the other codons that produce Leucine are:

UUA, UUG, CUU, CUC, CUA and CUG

So the code CUU could mutate to CUC, CUA or CUG and leucine would still be produced.

I don't get your question i am confused.
The answer would be CUC, the first two nucleotide should remain same and the 3rd one may vary between U and C most commonly for neutral mutation. So in the blank you'll put UC
