Of the many plots in A Midsummer Night’s Dream, which plot does Shakespeare focus on during the exposition and why?

the play by Bottom and his friends because they are funny

the Theseus and Hippolyta plot because they are the noble characters and appear onstage first

the four-lovers plot because it drives the action of the rest of the play

the fairies plot because the rest of the play wouldn’t happen if the fairies didn’t intervene
