The correct answer is option A, a capsid and genetic material
Reason -
The three major parts of a virus are as follows –
a) Protein Capsid – Virus genetic material(genome) is covered by a protein shell which is known as capsid.
b) Lipid Envelope – Further the Protein Capsid (also referred as nucleocapsid) is surrounded by a membrane called as envelope.
c) Viral genome – It mainly consists of single or double stranded DNA or RNA (carry the genetic material) which can be double or single stranded or may have some other form of structure.
