Solution

The correct option is A S1 is true but S2 is false
Nitrogen atom has five valence electrons. It achieves the nearest noble gas electronic configuration by sharing three electrons with another nitrogen atom. Therefore, between 2 nitrogen atoms, three electron pairs are shared to form a molecule. Hence, a triple bond is formed.
