Answer

Explanation:

Step1: Determine electron - domain number

Nitrogen in $NH_3$ has 3 bonding pairs (with 3 H atoms) and 1 lone - pair. So the total number of electron domains around N is 4.

Step2: Identify hybridization

When the number of electron domains is 4, the hybridization is $sp^3$. Nitrogen in $NH_3$ has 4 $sp^3$ hybrid orbitals, three of which are used for bonding with hydrogen atoms and one holds the lone - pair.

Answer:

D. four $sp^3$ orbitals
