d) accepts the blame for polonius’s death

a) he encourages Laertes to seek revenge against Hamlet.

Explanation:

In Shakespeare's "Hamlet," Claudius sees in Polonious's death the perfect opportunity to get rid of his nephew Prince Hamlet. In that matter, he stimulates Polonious' son Laertes to come back and take revenge against Hamlet. Actually, Claudius fears that Hamlet suspects that he murdered his father King Hamlet and soon married the queen to move on quickly and make people forget their former king. As a result, Claudius has plenty of reasons to do away with Hamlet and wants to make sure that he dies during the duel with Laertes.
