Strategy:
 Evaluate the structure, bonding, and chemical properties of Methane, Ammonia, and Water.

Statements:
- (A) All are  hybridized ( electron pairs). True.
- (B) Bond angles match  (),  (),  (). True.
- (C) Dipole moment order (nonpolar < polar < highly polar). True.
- (D) / are Lewis acids? No, they are bases (donors).
- (E)  in water is acidic/basic? Ammonia is a base.

Choices A, B, and C are correct.
