Assertion: Antiboitics like pencillin can be used to treat common cold.
Reason: Pencillin causes lysis of viral cells.

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

Answer

To analyze the given assertion and reason, we will break down the information step by step.

### Step 1: Understand the Assertion
The assertion states that "Antibiotics like penicillin can be used to treat common cold."
- **Analysis**: Common cold is primarily caused by viruses (like rhinoviruses). Antibiotics, including penicillin, are designed to combat bacterial infections, not viral infections. Therefore, this assertion is incorrect.

### Step 2: Understand the Reason
The reason states that "Penicillin causes lysis of viral cells."
- **Analysis**: Penicillin is an antibiotic that works by targeting bacterial cell walls, leading to bacterial cell lysis (destruction). It does not affect viral cells because viruses do not have cell walls and replicate differently than bacteria. Thus, this reason is also incorrect.

### Step 3: Conclusion
Since both the assertion and the reason are false, we conclude that the correct answer is that both statements are incorrect.

### Final Answer
Both the assertion and the reason are false.
