Answer:
Correct option : B
Explanation:
First compare 
with 
there are two lone pair in but only one lone pair presen in the so more lone pair means more repulsion and hence less bond bond angle beacuse of lone pair repulsion bonded atom come closer and hence bond angle decreased .
bond angle inversely proporional to repulsion so more repulsion means less bond angle
does no exist it exist only in the form of 
and here assuming 
because in case of 
difficult to compare bond angle because here two different type of bond angle is present.
there is no lone pair in the so here will no be any repulsion and hence bond will be more in as compared to
The answer is B charged particles
