What Was a Key Factor Contributing to the British Civil

What was a key factor contributing to the British civil wars, and how did it influence the events that first set off the war?

A) Charles I consistently refused to adopt the principle of absolutism and, as a result, caused widespread protests in London that he had given Parliament too much power.
B) Conflict among the kingdoms Charles I ruled made the war more imminent, leading to the formation of a Scottish rebel army.
C) Charles I got into a disagreement with France over taxes and trade, leading to the first major battle of the war known as the revolt of the Fronde.
D) To address the threat in England to the institution of monarchy, the continental European powers united forces and invaded England.
E) The Treaty of Westphalia granted England so little land that different parts of England began to turn on one another and form small armies to fight over the new territory.
