a messenger rna, ribosomal rna, plasma rna
b messenger rna, ribosomal rna, transfer rna
c messenger rna, cellular rna, transfer rna
d ribosomal rna, transfer rna, cellular rna

Explanation:

The three primary, well-defined types of RNA involved in fundamental cellular processes (gene expression and protein synthesis) are messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). The other terms like plasma RNA and cellular RNA are not recognized as distinct, standard types of RNA in this context.
