Assertion: If dot product and cross product of `vec(A)` and `vec(B)` are zero, it implies that one of the vector `vec(A)` and `vec(B)` must be a null vector.
Reason: Null vector is a vector with zero magnitude.

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

B

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

C

If assertion is true but reason is false
