Solution

The correct option is C
$l p - l p > l p - b p > b p - b p$

As we know, the lone pair tries to take more and more space. Therefore if two lone pairs are present, then there will be maximum repulsion. Then, comes the repulsion between lone pair and bond pair. The least repulsion will be between bond pair and bond pair.

$l p - l p > l p - b p > b p - b p$
