Solution

The correct option is A $C H_{3} - C H_{2}^{⊝} > N H_{2}^{⊝} > H - C \equiv C^{⊝} > ⊝ O H$
The conjugate base of strong acid is weaker and conjugate base of weak acid is stronger. So, decreasing order of basic strength: ${C H}_{3} - {C H}_{2}^{-}$ > ${N H}_{2}^{-}$ > $C H \equiv C^{-}$ > ${O H}^{-}$
