(B) George $Gamow$ was the first to suggest that the genetic code must be a triplet,meaning three nucleotides code for one amino acid. He argued that since there are only $4$ bases and $20$ amino acids,a triplet code ($4^3 = 64$ codons) is the minimum required to code for all $20$ amino acids. While $Nirenberg$ and $Matthaei$ experimentally proved the triplet nature of the code using synthetic $mRNA$ (poly-$U$),the theoretical possibility was first pointed out by $Gamow$.

The possibility of a three-letter genetic code was first suggested by:
