oliver cromwell was a supporter of the king.
oliver cromwell was a member of the nobility.

Option D, Oliver Cromwell was an enemy of the king, 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.  In 1653, he dissolved the Rump parliament because of its failure in the implementation of the reforms. He implemented his own ways to rule. Therefore, he is best described as the enemy of the king.

option d is correct. corroborated sources of historical evidence   is necessary to validate a claim about an event in history.

historians tend to use written sources, but audio and visual materials as well as artifacts are important objects that supply information to modern historians.

historical sources are usually divided into two categories: primary and secondary sources. depending on the historian's intent, some sources shift their designation. determining what type of sources toimplement, and the level of credibility and reliability of those sources, is a significant step in critical thinking for the historian.
