The correct option is
D Either DNA or RNA
An organelle is a membrane-bound structure seen in the cell that performs some specific functions. A virus is a very small infectious agent that can attack a host cell. They start replicating themselves by integrating their RNA or DNA into the host DNA once they enter the cell. A virus can be described as an assembly of proteins, genetic material like DNA or RNA that may or may not contain lipids.
So the correct answer is 'DNA or RNA'
