The correct answer is A. King claims that direct action must be used because powerful groups are unlikely to change on their own. This statement reflects King's belief that those in positions of power and privilege are often resistant to change and will not willingly give up their advantages. Therefore, direct action is necessary to challenge and pressure them into making changes.
