Solution

The correct option is B (i), (ii)
When there is back bonding from central to side atom change in hybridization takes place. Back bonding takes place when one atom has vacant orbital and one has lone pairs.
So central atom has a lone pair and side atom must have vacant orbital
So : $C C l_{3}^{-}$
$N (S i H_{3})_{3}$
$S p^{3} - S p^{2}$
