D. Mescaline

Answer

To determine which of the following drugs is a tranquilizer and sedative, we need to analyze each option based on their pharmacological effects.

1. **Understanding Tranquilizers and Sedatives**:
- Tranquilizers are drugs that have a calming effect, reduce stress, and help manage mental health issues. They affect the central nervous system and can induce sleep, which is why they are also classified as sedatives.

2. **Analyzing the Options**:
- **Sulfadiazine**: This is an antibiotic used to treat infections, specifically Toxoplasmosis. It does not have tranquilizing or sedative properties.
- **Papaverine**: This drug is primarily used for vasodilation, meaning it relaxes smooth muscles in blood vessels. It does not function as a tranquilizer or sedative.
- **Equanil**: This medication is used to treat symptoms of anxiety and nervousness. It has a calming effect, reduces stress, and can induce sleep, making it a tranquilizer and sedative.
- **Mesaline**: This drug alters perception and thinking, inducing an altered state of consciousness. It does not have tranquilizing or sedative properties.

3. **Conclusion**:
- After analyzing all options, we find that **Equanil** is the only drug that acts as both a tranquilizer and a sedative.

Thus, the correct answer is **Equanil**.
