What did parliament do soon after the death of oliver cromwell?
parliament went to war with scotland.
parliament restored the monarchy.
parliament banned the monarchy forever.
parliament imposed the protectorate.

Option B, Parliament restored the monarchy is the right answer.  

As a strict Puritan Oliver Cromwell, served as the Lord Protector of the Commonwealth of England, Ireland and Scotland from 1653 until his death. his son Richard succeeded him as the lord protector after his death. His lack of executive and military ability led his forced resignation in May 1659. this finally ended the Protectorate. Therefore, the lack of leadership of commonwealth led to the abandonment of the parliament and the monarchy in 1660 under Charles II.
