D. Quinine.

Answer

### Step-by-Step Solution:

1. **Identify the Question**: The question asks which drug is used to control malaria fever.

2. **Review the Options**: The options provided are:
- A) Penicillin
- B) DDT
- C) Streptomycin
- D) Quinine

3. **Analyze Each Option**:
- **Penicillin**: This drug is primarily used to treat bacterial infections, such as pneumonia. It is not effective against malaria, which is caused by a parasite.
- **DDT**: This is an insecticide used for controlling insect populations, particularly mosquitoes, but it is not a treatment for malaria.
- **Streptomycin**: This is another antibiotic used to treat bacterial infections, such as tuberculosis and some forms of pneumonia. It does not treat malaria.
- **Quinine**: This is a medication that has been used for centuries to treat malaria. It specifically acts against the asexual erythrocytic forms of the Plasmodium species that cause malaria.

4. **Determine the Correct Answer**: Based on the analysis, the correct answer is **Quinine**. It was the primary treatment for malaria until the introduction of chloroquine in the 1920s and is still used today, especially in cases of resistance to other treatments.

5. **Conclusion**: The drug that controls malaria fever is **Quinine**.
