Assertion (A). Ethylene induces ripening
Reason (R). Ethylene is a gaseous hormone

Options

A. A and R are true, R is correct explanation of A
B. A and R are true but R is not the correct explanation
C. A is true, R is false
D. A is false, R is true.

Answer

To analyze the given assertion and reason, let's break down the information step by step:

### Step 1: Understand the Assertion
- **Assertion (A)**: Ethylene induces ripening.
- Ethylene is known as a plant hormone that plays a crucial role in the ripening process of fruits. It is widely recognized for its ability to trigger the physiological changes that lead to ripening.

### Step 2: Understand the Reason
- **Reason (R)**: Ethylene is a gaseous hormone.
- Ethylene is indeed a gaseous plant hormone. It is unique among plant hormones because it exists in a gaseous state at room temperature, which allows it to diffuse easily through air and tissues.

### Step 3: Evaluate the Relationship
- Now, we need to evaluate whether the reason provided (R) correctly explains the assertion (A).
- While both statements are true (ethylene does induce ripening, and it is a gaseous hormone), the reason does not explain the assertion. The fact that ethylene is a gaseous hormone does not inherently explain why it induces ripening.

### Step 4: Conclusion
- Since both the assertion and the reason are true, but the reason does not provide a correct explanation for the assertion, the correct conclusion is:
- **Both assertion and reason are true, but the reason is not the correct explanation of the assertion.**

### Final Answer
- The correct option is: **Assertion and reason are true, but reason is not the correct explanation.**
