Assertion : vec(A)xxvec(B) is perpendicu...

Assertion : `vec(A)xxvec(B)` is perpendicular to both `vec(A)+vec(B)` as well as `vec(A)-vec(B)`.
Reason: `vec(A)+vec(B)` as well as `vec(A)-vec(B)` lie in the plane contanining `vec(A)and vec(B)`, but `vec(A)xxvec(B)` lies perpendicular to the plane containing A and B.

A

Assertion is True, Reason is True, Reason is a correct explantion for Assertion

B

Assertion is True, Reason is True, Reason is not a correct explanaition for Assertion

C

Assertion is True, Reason is False

D

Assertion is False, Reason is False.
