Genetic material of influenza virus is

Options

A. Single helix DNA
B. Double helix DNA
C. Double strand RNA
D. Single strand RNA

Answer

### Step-by-Step Solution:

1. **Identify the Virus**: The question asks about the genetic material of the influenza virus. Influenza is commonly known as the flu virus.

2. **Understand the Structure of Influenza Virus**: The influenza virus is spherical in shape and is enveloped, meaning it has an outer lipid bilayer.

3. **Examine the Components**: Within the lipid bilayer, there are spikes that are glycoproteins. These spikes are important for determining the subtypes of the influenza virus.

4. **Look at the Genetic Material**: The genetic material of the influenza virus is located within the virion. It consists of 8 strands of RNA.

5. **Determine the Type of RNA**: The RNA present in the influenza virus is single-stranded. Specifically, it is negative-sense single-stranded RNA.

6. **Select the Correct Answer**: Based on the information gathered, the genetic material of the influenza virus is single-stranded RNA. Therefore, the correct answer is option 4: single-stranded RNA.

### Final Answer:
The genetic material of the influenza virus is **single-stranded RNA**.
