correct option: A (The bond angle in NH3 is significantly smaller than the ideal bond angle of 109.5° because of the lone pair on the central atom.)

Explanation:

the bond angle in NH₃ is smaller than the ideal bond angle 109.5⁰ beacuse of lone pair bond pair repulsion or we can say bonding electron takes less space than non bonding electron (lone pair) due to this bond come closer to each other and hence bond angle decreases.
