Assertion Insectivorous plants get nitrogenous nutrition from the insects.
Reason IAA is growth promoter.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the assertion and reason question, we will follow these steps:

### Step 1: Analyze the Assertion
- The assertion states that insectivorous plants get nitrogenous nutrition from insects.
- Insectivorous plants, like the Venus flytrap, trap and digest insects to obtain nutrients, particularly nitrogen, which is essential for their growth.
- Therefore, the assertion is **true**.

### Step 2: Analyze the Reason
- The reason states that IAA (Indole-3-acetic acid) is a growth promoter.
- IAA is indeed a type of auxin, which is a plant hormone that promotes growth by stimulating cell elongation, division, and root formation.
- Thus, the reason is also **true**.

### Step 3: Determine the Relationship
- Although both the assertion and the reason are true, the reason does not explain why insectivorous plants obtain nitrogen from insects. The reason discusses the role of IAA in plant growth but does not relate to the nutritional strategy of insectivorous plants.
- Therefore, the reason is not the correct explanation for the assertion.

### Conclusion
- Both the assertion and reason are true, but the reason does not explain the assertion.
- The correct answer is **Option B**: Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
