Answer

To solve the question "In a cactus plant, food is made by:", we need to analyze the options provided and understand the structure and function of a cactus plant.

### Step-by-Step Solution:

1. **Understanding the Cactus Plant**:
- Cacti are a type of plant that are adapted to survive in arid environments. They are known for their thick, fleshy stems and reduced leaves.

2. **Analyzing the Options**:
- **A. Branches**: While branches are part of the cactus, they are not primarily responsible for photosynthesis.
- **B. Roots**: Roots primarily function to absorb water and nutrients from the soil, not to make food.
- **C. Leaves**: In cacti, leaves are reduced to spines to minimize water loss, so they do not play a role in photosynthesis.
- **D. Stem**: The stem of the cactus is green and contains chlorophyll, which is essential for photosynthesis. Therefore, the stem is responsible for making food.

3. **Conclusion**:
- The correct answer is **D. Stem**. The stem of the cactus carries out photosynthesis and is the primary site for food production in the plant.

### Final Answer:
**D. Stem**
