The compound which will have the lowest rate towards nucleophilic aromatic substitution on treatment with OH…

Aromatic nucleophilic substitution reaction takes place via the formation of a carbanion intermediate. Hence, the rate of reaction depends on the stability of the carbanion.

Electron withdrawing effect can stabilise the carbanion. The Electron withdrawing nature of the nitro group will be minimum at the meta position.

Hence the correct answer is
