Why it can not be row 2? The answer is E
row 2): CH2Cl2 is tetrahedral but the C is surrounded by both H and Cl atoms, so the dipole moments do NOT cancel out, making it POLAR
row 5): correct, P has no lone pairs of electrons and 5 e⁻ regions so it is trigonal bipyramidal, it’s also non polar since it’s surrounded only by the same type of element Cl, the dipole moments cancel out making it non-polar
Hope this helps!!
