Which of the following kill the organisms in the body (I.e bactericidal drug)?

Options

A. Penicillin
B. Ofloxacin
C. both a and b
D. none of these

Answer

To determine which of the given options are bactericidal drugs, we need to analyze the provided choices: "pencil" and "oplodaxin."

### Step-by-Step Solution:

1. **Identify the Options**: The question presents two options: "pencil" and "oplodaxin."

2. **Understand Bactericidal Drugs**: Bactericidal drugs are those that kill bacteria directly, as opposed to bacteriostatic drugs, which only inhibit bacterial growth.

3. **Research the Drugs**:
- **Pencil (Penicillin)**: This is a well-known antibiotic that is classified as a bactericidal drug. It works by disrupting the cell wall synthesis of bacteria, leading to cell lysis and death.
- **Oplodaxin**: This is not a commonly recognized antibiotic. It may be a fictional or less-known drug, and without specific information, we cannot classify it as bactericidal.

4. **Conclusion**: Based on the information, Penicillin is a bactericidal drug that kills bacteria, while Oplodaxin does not have enough information to classify it as such.

5. **Final Answer**: Therefore, the answer to the question is **Penicillin** (if it is indeed referring to Penicillin).
