Solution
The correct option is C Lipoprotein
A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. For some viruses, the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells. This lipid and protein structure is called the virus envelope, and is derived from the host cell membranes. Thus, option C is correct.
Viral envelope is not made of only protein, only lipids and mucilage. Thus, other options are wrong.
