AI Explanation
The correct answer is C. The atmospheric pressure line is indicated by line C in the pressure-volume diagram shown in the illustration MO-0035. This is because the atmospheric pressure, which is the pressure exerted by the weight of the Earth's atmosphere, is a constant reference point on the diagram, and is typically represented by a horizontal line. The other answer choices are incorrect because: A) Line A does not represent the atmospheric pressure line. B) Line B does not represent the atmospheric pressure line. D) Line de does not represent the atmospheric pressure line.
