Assertion: Antibiotics such as penicillin can be used to treat common cold.
Reason: Pencillin causes lysis of viral cells.

Options

A. If both Assertion and Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertin and Reason are true but the reason is not the correct explanation of the assertion, then mark (20.
C. If Assertion is true but Reason is false, then mark (3).
D. If both Assertion and Reason are false. Then mark (4).

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that antibiotics such as penicillin can be used to treat the common cold.
- **Hint**: Consider what causes the common cold.

2. **Identifying the Cause of Common Cold**: The common cold is primarily caused by viruses, not bacteria.
- **Hint**: Recall the difference between bacterial infections and viral infections.

3. **Understanding Antibiotics**: Antibiotics, including penicillin, are designed to target and kill bacteria. They do not have any effect on viruses.
- **Hint**: Think about the mechanism of action of antibiotics.

4. **Evaluating the Reason**: The reason given is that penicillin causes lysis of viral cells. This statement is incorrect because antibiotics do not act on viruses.
- **Hint**: Reflect on whether antibiotics can affect viral cells.

5. **Conclusion**: Since the assertion is incorrect (penicillin cannot treat the common cold) and the reason is also incorrect (penicillin does not cause lysis of viral cells), we conclude that both the assertion and the reason are false.
- **Hint**: Summarize the findings to determine the truth of both statements.

### Final Answer:
Both the assertion and the reason are false. The correct option is that both statements are incorrect.
