The correct option is B Synthesis of proteins
Protein synthesis is a two step process. In the first step, a molecule of mRNA is synthesized on DNA template through the process of transcription. In the second stage, the genetic message is translated into a linear chain of amino acids through the process of translation. In translation, other forms of RNA like tRNA and rRNA also participate. The rRNA are a component of ribosomes and tRNA bring the amino acids for binding as per the complementary codon-anticodon pairing or the genetic message present in the mRNA.
