| Assertion: An aircraft flies along the meridian, the potential develops at the ends of its wings. |
| Reason: Whenever there is change in the magnetic flux e.m.f. induces. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and 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.
E) If assertion is false but reason is true.
Correct Answer: A
