How does a virus cause a person to develop the common cold?
A
invades the host cell to reproduce
B
removes energy from the host cell
C
produces toxins in the host cell
D
protects the host cell from bacteria
Explanation: 

Detailed explanation-1: -Once a virus gets into a host’s body, it travels along the surfaces of cells until its proteins begin to bind with receptors on the cells. The virus and the cells then fuse, allowing the DNA or RNA inside the virus to enter the cells, where it begins to reproduce.

Detailed explanation-2: -The virus’s genome is uncoated from the protein and injected into the host cell. Then the viral genome hijacks the host cell’s machinery, forcing it to replicate the viral genome and produce viral proteins to make new capsids. Next, the viral particles are assembled into new viruses.
