Which has the highest nucleophilicity?

Question

Which has the highest nucleophilicity? (A) F- (B) OH- (C)  CH3- (D)  NH2-

A nucleophile is a chemical species that donates an electron pair to an electrophile to form a chemical bond in relation to a reaction Electronegativity - "greed for electrons" - is the opposite of nucleophilicity - "giving away electrons.
So less the electronegativity more the nucleophilicity of ion.

-^{-} C H_{3}

has the highest nucleophilicity. Nucleophilicity decreases as

C H_{3}^{-} > N H_{2}^{-} > O H^{-} > F^{-}
