The major theme of Paradise Lost is DISOBEDIENCE TO GOD'S COMMANDS. Paradise lost is an epic poem that talked about Adam and Eve and how they lost their God given paradise as a result of yielding to the devil's temptation. The devil decided to defile the man, who is newly created by God as a revenge on God for sending him and other fallen angels out of heaven and he went ahead and made Adam and Eve to sin against God.
A seems the most logical in this sense, since parents are portrayed (and majority do) sacrifice a lot so their children can live good and better lives than they did.
