Solution

The correct option is B mRNA
DNA is present in the nucleus and is transcribed into mRNA. Messenger RNAs (mRNAs) is transported to the cytoplasm where is serves as a template for protein synthesis and thus it transfers genetic information from DNA to ribosomes (the site for translation). Transfer RNAs (tRNAs) transfer the appropriate amino acid from amino acid pool of cytoplasm to a growing polypeptide chain during protein synthesis. Ribosomal RNAs (rRNAs) are structural constituents of ribosomes. snRNA serve in post transcriptional modification of hnRNA into mRNA. Thus, the correct answer is option B.
