B)tRNA
C)mRNA
D)snRNA

mRNA (messenger RNA) serves as a link between DNA (which contains the genetic information) and protein synthesis. mRNA carries the genetic information from the DNA to the ribosomes where it can be translated into a protein.

The other molecules listed are involved in various stages of protein synthesis but do not serve as the direct link between DNA and protein synthesis. rRNA (ribosomal RNA) is a component of the ribosome, where protein synthesis occurs. tRNA (transfer RNA) carries amino acids to the ribosome during protein synthesis. snRNA (small nuclear RNA) is involved in RNA splicing, a process that modifies mRNA before it is exported from the nucleus.
