Solution

The correct option is A $C H_{3} - C H_{2}^{⊝} > N H_{2}^{⊝} > H - C \equiv C^{⊝} > O H^{⊝}$
Conjugate base of strong acid is weak while conjugate base of weak acid is stronger.
Acidic strength of acid
$H O H > C H \equiv C H > N H_{3} > C H_{3} C H_{3}$
Hence, order of strength of base
$C H_{3} - C H_{2}^{⊝} > N H_{2}^{⊝} > C H \equiv C^{⊝} > O H^{⊝}$
