Nucleophilicity order in DMSO (polar aprotic) depends on charge and polarizability.

Hydrazine (NH₂–NH₂) > NH₃ → better nucleophile (statement B correct)

Phenoxide ion > Acetate ion → more basic due to resonance and delocalization (statement C correct)

SH⁻ and CH₃⁻ better nucleophiles than OH⁻ in DMSO (statement D correct)

Correct options: B, C, D
