D. A Sequence of three amino acids linked by peptide bonds.
Explanation:
Well, it cannot be A or C because those answers contain the letter T, otherwise, know as Thymine. Thymine is only found in DNA sequences, not it RNA. RNA sequences replace Thymine with Uracil, which brings me to the next point. It can't be answer choice B. because it contains an error in translation. The 3rd and 4th letter in, CG should translate to GC in the RNA strand, but it doesn't. This is why your answer is D.
