Assertion: An observer is moving due east and wind appears him to blow from north. Then the actual direction of air blow must be towards south-east
Reason: `vecV_(R)=vecV_(A)-vecV_(M)` where `vecV_(R)` is the relative velocity of wind w.r.t. man. `vecV_(A)=` actual velocity of wind (w.r.t. ground) and `vecV_(M)=` velocity of man w.r.t. ground.

A

If both assertion `&` Reason are True `&` the Reason is a corrrect explanation of the Asserion.

B

If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.

C

If Assertion is Trie but the Reason is False.

D

If both Assertion `&` Reason are false
