Solution

The correct option is B Genetic material
Prions are infectious proteins that have been misfolded. They have the ability to transmit their misfolded shape onto normal variants of the same protein. On the other hand, viruses are nucleoproteins made up of genetic material and a protein coat. Hence, viruses lack cellular structures like plasma membrane and cell wall.
