Solution

The correct option is A Polysome
A polysome is a single mRNA that is simultaneously being translated by many ribosomes. It results in the synthesis of multiple copies of a polypeptide. All the plastids of cells collectively are called as plastidome. Nucleosome is a basic unit consists of DNA wrapped around four proteins called histones. Polyhedral bodies are inclusion bodies that are associated with replication of certain insect viruses.
Thus, the correct answer is option B.
