E Correct answer
Explanation
  1. NH3 and PCl3 both molecules have one lone pair of electrons with trigonal pyramidal geometry.
    1. OF2 has two lone pair of electrons with bent geometry.
    2. SO3 has zero lone pair of electrons with trigonal planar geometry.
    3. CO2 has zero lone pair of electrons with linear geometry. XeCl2 has three lone pair of electrons with linear geometry. Hence, 1 and 4 statements are incorrect.
