According to Bronsted and Lowry's concept conjugate bases obtained from weak acids are strong.

Q. Which of the following order represent the order for the strength of base?

$C H_{3} C H_{2}^{-} > N H_{2}^{-} > H C \equiv C^{-} > O H^{-}$

$H - C \equiv C^{-} > C H_{3} C H_{2}^{-} > N H_{2}^{-} > O H^{-}$

$O H^{-} > N H_{2}^{-} > H C \equiv C^{-} > C H_{3} C H_{2}^{-}$

$N H_{2}^{-} > H C \equiv C^{-} > O H^{-} > C H_{3} C H_{2}^{-}$
