Your question is slightly not clear ... Can you show your attempt?
Aldol reaction can take place in acidic medium  also .Don't you think it is aldol followed by nucleophilic substitution in step II and III.What do you think?

If Reagent A were an amine, what would you form, and what would its utility be?
