Standard atmospheric pressure at sea level is approximately equivalent to: A) 76 cm of mercury (Hg). B) 29.9 inches of mercury (Hg). (Standard is approximation). C) 1013.2 millibars (Standard is imation). Since options A, B, and C are all valid ways to represent the standard atmospheric pressure at sea level, option D, "all the above," is the correct answer.
