Explanation:

• Option A: Uranium - lead dating is used for very old rocks (millions to billions of years), not 200,000 years.
• Option B: Carbon - nitrogen dating is not a common absolute dating method for rocks; carbon - 14 dating (carbon - nitrogen is incorrect terminology here) is for organic materials up to around 50,000 - 60,000 years.
• Option C: Potassium - argon dating is suitable for dating rocks that are hundreds of thousands to billions of years old, and 200,000 years falls within its range.
• Option D: The principle of inclusions is a relative dating principle, not an absolute dating method.

Answer:

C. Potassium/argon dating
