Help me pls :( determine the number of lone pair electrons on each H in NH3. Z of N=7, H=1

The correct option is;

A. 0

Explanation:

The ammonia molecule has four pairs of electron whereby being located around the central nitrogen atom is tetrahedral in shape.

Of the four pairs of electrons, three are the bonds between nitrogen and hydrogen, such that there is only one lone pair of electron in the ammonia molecule that is located on the central nitrogen atom

The one electron on each hydrogen atoms and one of the electrons on the nitrogen atom form a bonding pair of electrons, that is the bonding pair of electrons are shared by the two nuclei, hydrogen and nitrogen

Since a lone pair are a pair of electrons attached to only one nucleus, the hydrogen in ammonia has no lone pair of electrons.
