A. Natural selection
B. Intercropping
C. Hybridisation
D. Mixed cropping

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the process of improving crops by crossing two plants that have different desired traits.

2. **Identifying Key Terms**: The key terms in the question are "crop improvement," "crossing two plants," and "different desired characters."

3. **Exploring Options**: The options provided are:
- A) Natural selection
- B) Intercropping
- C) Hybridization
- D) Mixed cropping

4. **Analyzing Each Option**:
- **Natural Selection**: This is a process where organisms better adapted to their environment tend to survive and produce more offspring. It is not a method of crossing plants.
- **Intercropping**: This refers to growing two or more crops in proximity for various benefits, but it does not specifically involve crossing plants.
- **Hybridization**: This is the process of crossing two different plants to combine their desirable traits. This is the technique used in crop improvement.
- **Mixed Cropping**: This involves growing multiple crops together on the same land but does not involve crossing different plant species.

5. **Conclusion**: Based on the analysis, the correct term that describes the process of crop improvement by crossing two plants with different desired characters is **hybridization**.
