(a)
Interpretation: The stronger nucleophile from the given pair is to be identified.
Concept introduction: In nucleophilic substitution reaction, nucleophile takes the position of leaving group by attacking on the electron deficient carbon atom. The electron rich chemical species that contains negative charge or lone pair of electrons are known as nucleophile. The strong nucleophile is strong base whose conjugate acid has high
