Solution

The correct option is A Capsid
The outer protein coat of a virus is known as the capsid. It consists of several oligomeric structural subunits made of a protein called protomers which cover the nucleic acid which is present in the virus and protects it when virus inserts itself into the host. The capsid proteins also help the virus attach and penetrate the host cells thereby infecting the host. Hence option A is correct.
