Answer

Brief Explanations:

Carbon - nitrogen dating is not a common dating method. The principle of inclusions is a relative - dating method, not an absolute - dating one. Potassium/argon dating is useful for dating rocks that are older than about 100,000 years and is suitable for volcanic rocks. Uranium/lead dating is typically used for very old rocks (billions of years old). Since the rock is about 200,000 years old, potassium/argon dating is the most appropriate.

Answer:

C. Potassium/argon dating
