Explanation

To analyze the assertion and reason provided in the question, we can break it down into steps:

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that an American company is allowed to sell a 'new' variety of Basmati rice. This implies that the company has received some form of legal permission or patent to commercialize this rice.

2. **Historical Context**:
- In 1997, an American company did indeed receive patent rights for a variety of Basmati rice. This was a significant event as it raised concerns regarding the ownership and commercialization of traditional crops.

3. **Understanding the Reason (R)**:
- The reason states that Indian Basmati rice was crossed with semi-dwarf varieties and claimed as a novelty. This suggests that the American company modified the traditional Basmati rice by crossbreeding it with other rice varieties to create a new variety.

4. **Linking Assertion and Reason**:
- The assertion is true because the American company was granted permission to sell the new variety of Basmati rice. The reason is also true because the process of crossing Indian Basmati with semi-dwarf varieties was indeed a part of the development of this new variety.

5. **Conclusion**:
- Both the assertion and the reason are true. However, the reason does not directly explain the assertion. The assertion stands on its own based on the legal patent granted to the company, while the reason provides context about the modification of the rice variety.

### Final Answer:
- Both Assertion (A) and Reason (R) are true, but the reason does not directly support the assertion.
