D. Vigna sinensis.

Answer

To solve the question "Oil yielding legume is," we need to analyze the given options one by one to determine which one is an oil-yielding legume.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- Carthamus
- Glycine max
- Ricinus
- Vigna
- Sinensis

2. **Analyze Each Option**:
- **Carthamus**: This is commonly known as safflower. It is an oil-yielding plant, but it belongs to the family Asteraceae, which is not a legume family. Therefore, it is not a correct answer.

- **Glycine max**: This is the scientific name for soybean. Soybean is a legume and is known for its oil content, particularly rich in linoleic acid. Thus, this is a correct answer as it is both a legume and oil-yielding.

- **Ricinus**: Known as castor beans, this plant yields castor oil. However, it belongs to the family Euphorbiaceae, which is not a legume family. Hence, this option is incorrect.

- **Vigna**: This refers to a genus that includes cowpea (Vigna unguiculata), which is a legume. However, cowpea is primarily consumed for its protein content and does not yield oil. Therefore, this option is also incorrect.

3. **Conclusion**: The only option that is both a legume and yields oil is **Glycine max** (soybean).

### Final Answer:
The oil-yielding legume is **Glycine max**.
