Solution

The correct option is E I- tRNA; II- rRNA; III- mRNA
Transfer RNAs (tRNAs) read the genetic information present in form of triplets in the mRNA and interpret it as an amino acid to transfer the appropriate amino acid from cytoplasmic pool to a growing polypeptide chain. Ribosomal RNAs (rRNAs) are structural constituents of ribosomes that provide the site for proteins synthesis and binds to mRNA. Messenger RNAs (mRNAs) specify the amino acid sequence of one or more polypeptides, thus it contains the genetic information for protein synthesis. Thus, the correct answer is option E.
