We can directly determine from the options by selecting every option and determining whether it satisfies the given conditions.
Or actual way of solving according to me is this: let vector be ai^ + bj^ + ck^
Scalar triple product of this vector with the two vectors lying in its plane will be zero.This will give 1st equation.
Also, dot product with the vector perpendicular to it will be zero. This will give second equation.
As it is unit vector so
,√{ a^2 + b^2 + c^2 }= 1
This is 3rd equation. As there are 3 equations and 3 variables , solve to find a,b,c
