Assertion: Interferons help eliminate viral infections.
Reason: Interferons released by infected cells reach the nearby uninfected cells and make them resistant to viral infection.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Interferons help eliminate viral infections." This is true because interferons are proteins produced by virus-infected cells that play a crucial role in the immune response against viral infections.

2. **Understanding the Reason**: The reason states that "Interferons released by infected cells reach the nearby uninfected cells and make them resistant to viral infection." This is also true. When a cell is infected by a virus, it releases interferons, which then bind to the receptors on neighboring uninfected cells, triggering a protective response that makes them more resistant to future viral infections.

3. **Connecting Assertion and Reason**: Both the assertion and the reason are true statements. The reason provides a valid explanation for the assertion. Interferons indeed help eliminate viral infections by making nearby uninfected cells resistant to the virus.

4. **Conclusion**: Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that the correct answer is that both statements are true, and the reason is the correct explanation of the assertion.

### Final Answer:
Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
