Assertion: vecAxxvecB is perpendicular t...

Assertion: `vecAxxvecB` is perpendicular to both `vecA+vecB` as well as `vecA-vecB`.
Reason: `vecA+vecB` as well as `vecA-vecB` lie in the plane containing `vecA` and `vecB`, but `vecAxxvecB` lies perpendicular to the plane containing `vecA` and `vecB`

A

If both assetion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If the assertion and reason both are false.
