Which one of the following pairs is correctly matched with regard to the codon and the amino acid coded by it ?

Which one of the following codons codes for the same information as $UGC$

In $mRNA, AUG$ is the initiation codon and $UAA, UAG$ and $UGA$ are termination codons, therefore polypeptide cannot be synthesized beyond any of these triplets to the end of $mRNA$. Then which one of the following $mRNA$ can be translated completely

Whose experiments cracked the $DNA$ and discovered unequivocally that a genetic code is a “triplet”?

Assumption that genetic code is a triplet was suggested by
