Complete answer:
The civil war between Charles I and the British Parliament was the outcome of the refusal of any support by the British Parliament to Charles I in a war against Scots.The reign of King Charles I, who was a very religious person began in the year 1625. King Charles believed that he was King by the decision of God, so, no one could challenge or question the decisions made by him. This ideology and his deeply religious nature was opposed by some of the people who thought of limiting or restricting the Royal authority and the common people and their representatives or a parliament should be involved for the proper governance of a nation. King Charles and his lack of money was a major factor which led to the onset of the Civil war against the British Parliament. King Charles I demanded the British Parliament to raise funds in his war against Scots at various time periods. The British Parliament directly refused to provide any financial assistance to King Charles I, which led him to pay huge amounts of money to Scottish Covenanters after his defeats in various wars. This made Charles I to start a civil war against the British Parliament in the year 1642 after he entered the House of Commons. The civil war ended in the year 1649 with the victory of the British Parliament and the death of King Charles I, in which he was beheaded on 30th January 1649.

Hence, the correct answer is option (A).

Note:King Charles I started a civil war against the British Parliament due to lack of any financial assistance from the Parliament for different wars, and it started in 1642 and ended in 1649 with his death sentence.
