Explanation:

• Option A: Both archaea and bacteria are unicellular, so A is incorrect.
• Option B: Both archaea and bacteria are prokaryotes (lack a nucleus), so B is incorrect.
• Option C: Archaea are known as extremophiles and can survive in extreme environments (like high temperature, high salinity) that most bacteria cannot tolerate, so C is correct.
• Option D: Both archaea and bacteria use DNA as their genetic material, so D is incorrect.
