You may find the electron diagram of ammonia and the ammonium ion in the attached picture.
Explanation:
Ammonia NH₃ have covalent bonds with the hydrogen atoms in which for each bond one electron comes from nitrogen atom (blue dot) and the other from the hydrogen atom (red dot). You may see that the nitrogen remains with the lone pair of electrons that does not participate in bonding.
Ammonia NH₃ have a basic character and is able to accept a proton H⁺ from an acid to form the ammonium ion NH₄⁺. The fourth bond formed its called a coordinative-covalent bond that is created only with the nitrogen lone pair of electrons (blue dots).

Answer: C) Bent or angular, polar
Explanation:
The central atom oxygen has two lone pairs and two bond pairs in . The number of electron pairs are 4, that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral. But as there are two lone pair of atoms around the central oxygen atom, repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent shape.
The compound is polar as the net dipole moment of oxygen - fluoride bonds do not cancel each other out.
