Assertion : Viruses that infect bacteria are called bacteriophages.
Reason : Bacteriophages are devoid of capsid.

Options

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

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "Viruses that infect bacteria are called bacteriophages."
- This statement is true. Bacteriophages, often referred to as phages, specifically target and infect bacterial cells.

2. **Understanding the Reason:**
- The reason provided is "Bacteriophages are devoid of capsid."
- This statement is false. Bacteriophages do have a capsid, which is a protein coat that encases their genetic material. The capsid is essential for the protection of the viral DNA or RNA and for the infection process.

3. **Conclusion:**
- Since the assertion is true and the reason is false, we conclude that the correct relationship is that the assertion is correct, but the reason is incorrect.

4. **Final Answer:**
- Therefore, the correct option is that the assertion is true and the reason is false.
