Assertion:Association areas are neither clearly sensory nor motor in function.
Reason:Association areas are responsible for complex functions like intersensory associations, memory and communication.

Options

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

Explanation

To analyze the given assertion and reason, we will break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Association areas are neither clearly sensory nor motor in function."
- This means that these areas do not fit neatly into the categories of sensory (which process incoming sensory information) or motor (which control voluntary movements).

2. **Understanding the Reason**:
- The reason provided is that "Association areas are responsible for complex functions like inter-sensory associations, memory, and communication."
- This indicates that association areas play a crucial role in higher cognitive functions, integrating various sensory inputs and facilitating communication and memory.

3. **Evaluating the Truth of the Assertion**:
- The assertion is true. Association areas are indeed regions of the cerebral cortex that do not have a specific sensory or motor function but are involved in integrating and processing information.

4. **Evaluating the Truth of the Reason**:
- The reason is also true. Association areas are involved in complex functions such as memory, communication, and inter-sensory associations.

5. **Determining the Relationship**:
- While both the assertion and reason are true, the reason does not directly explain the assertion. The assertion describes the nature of association areas, while the reason describes their functions. Therefore, the reason is not a correct explanation for the assertion.

6. **Conclusion**:
- Based on the evaluation, the assertion is true, the reason is true, but the reason is not the correct explanation of the assertion. Thus, the answer is option B.
