Solution

The correct option is B CH3COO<OH<NH2
More stable the anion, less will be its nucleophilicity. Acetate is the most stabilised ion since it has equivalent resonance structures. Electronegativity of O is greater than N hence it can accomodate negative charge more easily. Thus the order will be: CH3COO<OH<NH2
