The D_z² and D_x² - _y² Orbitals Are Higher in Energy

The d_z² and d_x² - _y² orbitals are higher in energy than the d_xy, d_xz, and d_yz orbitals in an octahedral complex because these two orbitals ________

A) do not point directly at ligands.
B) point directly at ligands.
C) occupy larger volumes than the other three orbitals.
D) are in the same plane and repel one another.
E) occupy smaller volumes than the other three orbitals.
