Correct Answer
C rRNA
D snRNA
Correct Answer

Option B is the correct answer.

Detailed Explanation

Transfer RNA (tRNA) molecules have an anticodon sequence that base-pairs with a complementary codon on mRNA. Each tRNA carries a specific amino acid at its 3' end, delivering it to the growing polypeptide chain at the ribosome.

Hint

It's the 'adapter' molecule between mRNA and amino acids.
