Consider a plane `pi:vecr*vecn=d` (where `vecn` is not a unti vector). There are two points `A(veca)` and `B(vecb)` lying on the same side of the plane.
Q. Reflection of `A(veca)` in the plane `pi` has the position vector :

A

`veca+(2)/((vecn)^(2))(d-veca*vecn)vecn`

B

`veca-(1)/((vecn)^(2))(d-veca*vecn)vecn`

C

`veca+(2)/((vecn)^(2))(d+veca*vecn)vecn`

D

`veca+(2)/((vecn)^(2))vecn`
