Answer

To determine the classification of Cimetidine (Tegamet) and Ranitidine (Zantac), we can analyze the options provided and the functions of these drugs.

### Step-by-Step Solution:

1. **Understanding the Drugs**:
- Cimetidine (Tegamet) and Ranitidine (Zantac) are both medications that are primarily used to reduce stomach acid production.

2. **Analyzing the Options**:
- **A. Analgesics**: These are drugs used to relieve pain (e.g., aspirin, ibuprofen). Cimetidine and Ranitidine do not primarily serve this purpose.
- **B. Tranquilizers**: These are used to treat anxiety and stress. Cimetidine and Ranitidine are not classified as tranquilizers.
- **C. Antacids**: Antacids are substances that neutralize stomach acidity. Cimetidine and Ranitidine are not traditional antacids but are histamine receptor antagonists that reduce acid production, which can be related to the treatment of acid-related conditions.
- **D. Antidepressants**: These are used to treat depression and anxiety disorders. Cimetidine and Ranitidine do not fall into this category.

3. **Correct Classification**:
- Cimetidine and Ranitidine are classified as **histamine H2 receptor antagonists**. They are used to treat conditions such as peptic ulcers and gastroesophageal reflux disease (GERD) by decreasing the amount of acid produced by the stomach.

4. **Conclusion**:
- The correct answer is **C. Antacids**, as they are used to treat conditions related to excessive stomach acid, even though they are specifically H2 receptor antagonists.

### Final Answer:
Cimetidine (Tegamet) and Ranitidine (Zantac) are classified as **C. Antacids**.
