Imagine that NASA discovered a prokaryote-like organism. Initial experiments indicated they use the same DNA → RNA → protein system as life on Earth, except that
there are only 2 bases (A and T) in the Martian DNA, and
there are only 17 amino acids found in Martian proteins.
Based on this information, what is the minimum size of a codon for these hypothetical organisms?

Explanation:

your answer would be a, maximum exploitation of resources.
