Consider the following statements:
(A) Electron density in the \( \mathrm{XY} \) plane in \( 3 \mathrm{~d}_{\mathrm{x}^{2}-\mathrm{y}^{2}} \) orbital is zero.
(B) Electron density in the \( \mathrm{XY} \) plane in \( 3 \mathrm{~d}_{\mathrm{z}^{2}} \) orbital is zero.
(C) \( 2 \mathrm{~s} \) orbital has one nodal surface.
(D) For \( 2 p_{z} \) orbital, \( X Y \) is the nodal plane.
Which of these are incorrect statements?
(a) \( \mathrm{A} \& \mathrm{C} \)
(b) \( \mathrm{D} \& \mathrm{C} \)
(c) Only B
(d) A, B
