Assertion :
Double fertilisation is a characteristics feature of angiosperms Reason
Double fertilsation involves triple fusion.

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "Double fertilisation is a characteristic feature of angiosperms."
- This is true because double fertilization is a unique process that occurs only in flowering plants (angiosperms).

2. **Understanding the Reason:**
- The reason provided is that "Double fertilisation involves triple fusion."
- This statement is also true. In double fertilization, one male gamete fertilizes the egg, while the other male gamete fuses with two polar nuclei, resulting in a triploid endosperm. This process is referred to as triple fusion.

3. **Connecting Assertion and Reason:**
- The assertion and reason are both correct. The reason provides a correct explanation of the assertion because the process of double fertilization inherently includes the mechanism of triple fusion.

4. **Conclusion:**
- Since both the assertion and reason are correct, and the reason explains the assertion, the correct answer is that both statements are true and the reason is the correct explanation of the assertion.

**Final Answer:**
- The correct option is: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
