C. aspirin
D. chloramphenicol

Answer

To determine which option is a broad spectrum antibiotic, we need to analyze the given options based on their classifications and uses. Here’s a step-by-step solution:

### Step 1: Understand the Definition of Broad Spectrum Antibiotics
Broad spectrum antibiotics are medications that are effective against a wide range of bacteria, including both gram-positive and gram-negative bacteria. This is in contrast to narrow spectrum antibiotics, which target specific types of bacteria.

**Hint:** Look for antibiotics that can treat a variety of bacterial infections rather than those that are limited to specific bacteria.

### Step 2: Analyze the Options
1. **Procaine**: This is primarily an anesthetic used to numb an area before surgery. It is not classified as an antibiotic, and it has a narrow range of action.

**Hint:** Identify whether the option is an antibiotic or not.

2. **Plasmoquin**: This medication is used for the treatment of malaria, which is caused by parasites, not bacteria. Therefore, it is not an antibiotic and has a narrow spectrum of action.

**Hint:** Consider the type of infections the medication is used for.

3. **Aspirin**: This is an antipyretic and analgesic used to reduce fever and relieve pain. It is not an antibiotic and does not have antibacterial properties.

**Hint:** Check if the option is known for treating bacterial infections.

4. **Chloramphenicol**: This is a well-known broad spectrum antibiotic. It is effective against a variety of bacteria, including both gram-positive and gram-negative types.

**Hint:** Look for the option that explicitly states its effectiveness against a wide range of bacteria.

### Step 3: Conclusion
Based on the analysis, **Chloramphenicol** is the only option that qualifies as a broad spectrum antibiotic.

### Final Answer
The broad spectrum antibiotic among the given options is **Chloramphenicol**.
