Nitrogen has three electrons in its outermost shell and hydrogen has 1. 3 hydrogen atoms combine with 1 nitrogen atom to make ammonia. These bonds are single bonds.
Single bond: When two atoms share one electron pair between each other, then they are said to be bonded by single covalent bond, denoted by single dash joining the atoms.
Single bond: When two atoms share one electron pair between each other, then they are said to be bonded by single covalent bond, denoted by single dash joining the atoms.

Explanation:
Structure of Ammonia (NH3):
Ammonia (NH3) is a compound composed of one nitrogen atom and three hydrogen atoms. The nitrogen atom is connected to each hydrogen atom through a single bond, resulting in a pyramid-like structure. Each hydrogen atom forms a single covalent bond with the nitrogen atom, and the nitrogen atom has one lone pair of electrons.
Covalent Bonding:
In covalent bonding, atoms share electrons to form a stable electron configuration. A single bond consists of two electrons being shared between two atoms. In the case of ammonia, each hydrogen atom shares one electron with the nitrogen atom, resulting in three single bonds.
Explanation of Answer:
The correct answer is option 'D' - Only single bonds. Ammonia (NH3) contains three single bonds and no double or triple bonds. Each hydrogen atom forms a single bond with the nitrogen atom, resulting in a total of three single bonds.
Key Points:
- Ammonia (NH3) has a pyramid-like structure.
- It contains one nitrogen atom and three hydrogen atoms.
- Each hydrogen atom forms a single bond with the nitrogen atom.
- There are no double or triple bonds in ammonia.
- The correct answer is option 'D' - Only single bonds.
