Explanation:

One of the two electrons in the lower energy s orbital is moved up to the empty p orbital. The four orbitals are hybridized, that is the orbitals are averaged so that all four orbitals are the same. The four orbitals are same in energy and geometric shape.

To move one electron into an orbital with a higher energy level and averaging the four new orbitals requires more energy or an excited state.
