The correct answer is C.
Cardinal Richelieu (1585 – 1642) was a French bishop, known for his title as king's "Chief Minister" or "First Minister". He intended to consolidate and centralize power in the figure of the monarchy and also to defeat domestic factions. For example, the Huguenot faction originated due to the religious divisions that existed in France at the time.
Huguenots controlled a military force and started a rebellion, supported by the British king, that declared the war on France too. The Cardinal in person commanded the French army in order to regain dominance over the cities and territories that were under the control of the Huguenots.
