B. Ribosomal RNA

C. Messenger RNA

D. Nuclear RNA

Answer is A because of The Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein ...

Answer is A because I said so
