Consider the following statements.
I. All meta-directing groups are deactivating groups.
II. The activating substituents make the benzene ring more reactive towards S_E reaction.
III. Carbonyl groups are moderately deactivating substituents and withdraw electrons both inductively and by resonance.
Select the correct statements.

.The deactivating groups deactivate the ring by the inductive effect in the presence of an electronegative atom that withdraws the electrons away from the ring. ... Halogens are an exception of the deactivating group that directs the ortho or para substitution.

An electron donating group (EDG) or electron releasing group (ERG, Z in structural formulas) is an atom or functional group that donates some of its electron density into a conjugated π system via resonance (mesomerism) or inductive effects (or induction)—called +M or +I effects, respectively—thus making the π system more nucleophilic

A carbonyl group such as an aldehyde is a deactivating group as it withdraws electron density by both the inductive effect (through the sigma bonds) and the resonance effect which involves pi systems
