RNA stands for ribonucliec acid. It is genetic material in some organisms like viruses. It is of three types, namely mRNA, rRNA and tRNA. mRNA contain a copy of the instructions that a gene carries.

What is translation?

Translation is the process of formation of protein by mRNA.  

In this process the gene encodes a protein, and instructions are given for making protein.

mRNA plays main role in protein synthesis, as it contain a copy of the instructions that a gene carries.

Thus, the correct option is A.
