C. if assertion is true statement but reason is false then mark
D. if both assertion and reason are flase statements then mark

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that hybrid seeds must be produced every year because seeds collected from hybrid plants do not maintain hybrid characteristics when sown subsequently.

2. **Understanding Hybrid Seeds**: Hybrid seeds are produced from the crossbreeding of two different parent plants. This process aims to combine desirable traits from both parents, resulting in a seed that exhibits these hybrid characteristics.

3. **Sexual Reproduction in Hybrid Plants**: When hybrid seeds are planted, they grow into plants that will undergo normal sexual reproduction. This means that the offspring produced from these plants will not be identical to the hybrid parent plants.

4. **Result of Sexual Reproduction**: Sexual reproduction introduces genetic variation due to the recombination of alleles. As a result, the seeds produced by hybrid plants will show segregation of traits, meaning that the offspring may express a mix of traits from both parent plants rather than retaining the hybrid characteristics.

5. **Conclusion on the Assertion**: Since the seeds collected from hybrid plants do not maintain the desired hybrid traits when sown, the assertion is true. Hybrid seeds must be produced every year to ensure the desired characteristics are present in the new plants.

6. **Understanding the Reason**: The reason provided states that hybrid seeds show segregation of traits. This is also true because the process of sexual reproduction leads to the mixing of genetic material, resulting in offspring that may exhibit a variety of traits.

7. **Linking Assertion and Reason**: The reason correctly explains the assertion. Since hybrid seeds show segregation of traits due to sexual reproduction, the assertion that hybrid seeds must be produced annually to maintain desired traits is justified.

8. **Final Conclusion**: Both the assertion and reason are true, and the reason is a correct explanation of the assertion.
