Answer:
D. The lone pair forces bonding atoms away from itself.
Step-by-step explanation:
The lone pairs are found in the outermost shell thereby making sharing of electrons easier. Lone pairs which are found in a covalent bond creates a bond angle which makes it a determinant of the bond angle.
The lone pairs which are negatively charged repulses the bond pairs thereby creating a distortion in the shape of the molecule.
The lone pairs creates the distortion by forcing bonding atoms away from itself.
