Question
Which of the following is a primary characteristic of organisms classified under Archaea, as described in the document?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The document states that Archaea are 'Single-celled organisms (Unicellular)' and 'Prokaryotes'. Options A and B are incorrect as they are single-celled and prokaryotic. While they can be autotrophs (e.g., Methanogen bacteria), D is not a primary defining characteristic over C.
Hint
Think about the basic cell structure and number of cells for Archaea.
