Correct option is C
Chicken pox is caused by the Varicella zoster virus (VZV), which belongs to the Herpesviridae family. It is a highly contagious virus that causes an itchy, blister-like rash, fever, and malaise. After the initial infection, the virus becomes dormant in the dorsal root ganglia and can reactivate later in life as herpes zoster (shingles).
Explanation of options: (a) Paramyxovirus – This virus is responsible for diseases like measles and mumps, not chicken pox. (b) Myxovirus – A general term previously used for influenza viruses; not associated with chicken pox. (c) Varicella zoster – This is the correct answer. It causes chicken pox primarily in children and shingles in adults. (d) Herpes zoster – This is the reactivated form of the varicella zoster virus causing shingles, not chicken pox.
