Which of the following compounds would undergo Diels-Alder reaction with dienophile (e.g., Maleic anhydride) ?

Explanation

It involves the addition of a conjugated diene (having two alternate `pi`- bonds) to an unsaturated compound (alkene or alkyne) containing an electron withdrawing group usually called dienophile (diene loving) to form six memebered cylic alkenes (usually called Diel.s Alder adduct). For example,
