Assertion : In the phenomenon of mutual induction, self induction of each of the coils persists.
Reason : Self induction arises when strength of current in same coil changes. In mutual induction, current is changing in both the individual coils.

Options

A. If both Assertion and Reason are corrent and Reason is the corrent explanation of Assertion.
B. If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is ture.

Explanation

To solve the question regarding the assertion and reason related to mutual induction and self-induction, we can break it down step by step.

### Step 1: Understand the Assertion
The assertion states that in the phenomenon of mutual induction, the self-induction of each of the coils persists.
- **Explanation**: Mutual induction occurs when two coils are placed close to each other, and a change in current in one coil induces an electromotive force (EMF) in the other coil. However, each coil also has its own self-inductance, which means that when the current in a coil changes, it induces an EMF in itself as well. Therefore, the assertion is correct.

### Step 2: Understand the Reason
The reason provided states that self-induction arises when the strength of current in the same coil changes, and in mutual induction, the current is changing in both individual coils.
- **Explanation**: Self-induction indeed occurs due to a change in current in the same coil, creating a magnetic field that induces an EMF opposing the change in current. In mutual induction, the current change in one coil affects the other coil due to the magnetic field created by the first coil. Thus, the reason is also correct.

### Step 3: Evaluate the Relationship Between Assertion and Reason
Now we need to determine if the reason correctly explains the assertion.
- **Analysis**: While both the assertion and reason are correct, the reason does not specifically explain why self-induction persists in the phenomenon of mutual induction. The reason focuses on the change of current in both coils rather than explaining the persistence of self-induction in each coil.

### Conclusion
Both the assertion and the reason are correct, but the reason is not the correct explanation for the assertion. Therefore, the correct answer is that both statements are true, but the reason is not the correct explanation for the assertion.

### Final Answer
Assertion: True
Reason: True
Explanation: Reason does not correctly explain the assertion.
