Answer:
a) phenylalanine
Explanation:
A triplet codon results into a particular amino acid. mRNA is read in 5' to 3' direction during translation. tRNA carrying an amino acid enters the A site first. Then a peptide bond is formed between the new and old amino acid. The polypeptide along with the tRNA moves to P site while the now empty old tRNA moves from P to E site and exits. Hence a tRNA is first in A site followed by P site and then finally E site.
Here, a tRNA with histidine amino acid is present in the P site. From the given sequence, only CAU codon can result into histidine. So if CAU region is present in P site that means that UUU will be present in A site. UUU codes for phenylalanine amino acid so the tRNA entering the A site will carry phenylalanine.

More confident in the results
the others options could be valid but there is the need for more information to conclude in another hand, more confident in results is the most general case, if the repeating test brings back the same results.
