Assertion : Somatic hybridisation is a process where protoplasts of two desired plants can be fused to develop improved plants
Reason : Cross breeding can also induce variability

Options

A. Both assertion and reason are true but reason is the correct explanation of assertion.
B. Both assertion and reason are true but reason is not the correct explanation of assertion.
C. Assertion is true but reason is false.
D. Both assertion and reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that somatic hybridization is a process where protoplasts (the living part of a plant cell without the cell wall) of two desired plants can be fused to develop improved plants.
- This process is a form of genetic manipulation that allows for the combination of genetic material from different plant species or varieties to create hybrids with desirable traits.

2. **Understanding the Reason**:
- The reason provided states that cross-breeding can also induce variability.
- Cross-breeding involves mating individuals from different breeds or species to produce offspring with varied genetic traits. This method is commonly used in agriculture and animal husbandry to enhance certain characteristics.

3. **Evaluating the Assertion and Reason**:
- Both the assertion and the reason are indeed true statements. Somatic hybridization is a recognized technique in plant biotechnology, and cross-breeding is a well-established method for inducing genetic variability.
- However, the reason does not directly explain the assertion. Somatic hybridization is a specific technique involving protoplast fusion, while cross-breeding is a broader method that does not involve protoplasts.

4. **Conclusion**:
- Therefore, the correct conclusion is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Final Answer:
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
