6. Ligands approaching in a square planar pattern cause some orbitals to be raised in energy. How many orbitals are on the highest energy level?

a. A) 1
b. B) 2
c. C) 3
d. D) 4
e. E) 5

Isn't that 2. The 5 d orbitals are divided into the dx^2-y^2 and dz^2 at the top energy level and the dxy dxz and dyz orbitals at the bottom.
