Which of the following contains the maximum number of lone pairs on the central atom?

Which species is planar?

The three-dimensional structure of $CH_4$ is given below. The bonds are labelled as $W, X, Y$ and $Z$. What are the bonds lying in the plane $(A)$,projecting out of the plane away from the observer $(B)$ and projecting out of the plane towards the observer $(C)$?
