• A. Orthomyxoviridae
• B. Papoviridae
• C. Retroviridae
• D. Parvoviridae

Hint:

Influenza viruses are RNA viruses classified under the Orthomyxoviridae family, characterized by a segmented RNA genome and high mutation rates.

Answer 1

The Correct Option is A

Step 1: Understanding the influenza virus. Influenza viruses are RNA viruses that cause seasonal flu in humans and other animals. These viruses are characterized by their segmented, single-stranded RNA genome. 

Step 2: Family classification of influenza viruses. Influenza viruses belong to the family Orthomyxoviridae. This family includes Influenza A, B, and C viruses, which are responsible for respiratory infections. 

Step 3: Why other options are incorrect. 
- (B) Papoviridae: Includes double-stranded DNA viruses, such as papillomaviruses and polyomaviruses. 
- (C) Retroviridae: Includes RNA viruses like HIV that use reverse transcriptase for replication. 
- (D) Parvoviridae: Includes small DNA viruses, such as parvovirus B19.
