Solution

The correct option is D snRNA
A polyribosome is also called as polysome. This structure is formed by the complex of two or more ribosomes. This structure is used to translate the mRNA meolecule to form many polypeptide chains. These type of ribosomal structures are useful for the translation of the types of RNA like the mRNA, tRNA and the rRNA. The polysomes are not required for the translation of the snRNA. snRNA are the small nuclear RNA structures which are confined to the nucleus. They are involved in the splicing processes. There is no activity of the polysome on these type of RNA.
Thus, the correct answer is option D.
