A : Sense organs, do not interpret the stimulus, it is done by brain.
R : Sense organs are transducers. They transform the energy of a stimulus to the energy of nerve impulses.

Options

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

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that sense organs do not interpret the stimulus; this function is performed by the brain.
- This is correct because sense organs (like eyes, ears, skin, etc.) are responsible for detecting stimuli but do not process or interpret the information. The interpretation occurs in the brain.

2. **Understanding the Reason (R)**:
- The reason given is that sense organs are transducers, meaning they convert one form of energy into another. Specifically, they transform the energy of a stimulus (like light, sound, or pressure) into the energy of nerve impulses.
- This is also correct as sense organs take the external stimuli and convert them into electrical signals (nerve impulses) that can be processed by the nervous system.

3. **Analyzing the Relationship Between A and R**:
- Since both the assertion and the reason are true, we need to determine if the reason correctly explains the assertion.
- The reason explains how sense organs function as transducers, which is essential for the assertion that they do not interpret stimuli but rather relay information to the brain.

4. **Conclusion**:
- Both the assertion and the reason are true, and the reason provides a correct explanation for the assertion. Therefore, the correct answer is that both A and R are true, and R is the correct explanation of A.

### Final Answer:
- The correct option is: **Option 1** (Both assertion and reason are true, and reason is the correct explanation of assertion).
