If the symbol X represents a central atom, Y represents outer atoms, and Z represents lone pairs on the central atom, the struct

ure A central X atom has two lone pairs. Two Y atoms are attached to X with single bonds, could be abbreviated as XY2Z2.
Classify these structures by the hybridization of the central atom.
