a messenger rna

b transfer rna

c ribosomal rna

Explanation:

Ribosomal RNA (rRNA) is a type of RNA that combines with proteins to form ribosomes, the cellular structures responsible for protein assembly. Messenger RNA (mRNA) carries genetic instructions for protein synthesis, while Transfer RNA (tRNA) delivers amino acids to ribosomes during this process.
