Consider the following statements regarding the repulsive interactions in VSEPR theory: (A) \( \text{Lone pair (lp)} - \text{Lone pair (lp)} > \text{Lone pair (lp)} - \text{Bond pair (bp)} > \text{Bond pair (bp)} - \text{Bond pair (bp)} \) (B) The presence of lone pairs on the central atom causes deviations from ideal bond angles. (C) In \( \text{H}_2\text{O} \), there are two lone pairs and two bond pairs on the central oxygen atom. (D) In ammonia, the \( \text{H}-\text{N}-\text{H} \) bond angle is \( 109.5^\circ \). Choose the correct answer from the options given below:

1. A
   (B), (C) and (D) only
2. B
   (A), (B) and (C) only
3. C
   (A) and (D) only
4. D
   (A), (B), (C) and (D)
