A 760.0
B 938.9
C 1000.0
D 1013.2
AI Explanation

The correct answer is D) 1013.2 millibars. The standard atmospheric pressure at sea level is 1013.2 millibars (mb) or 29.92 inches of mercury (inHg). This value is widely recognized as the standard atmospheric pressure and is used as a reference point in many applications, including weather reporting and aviation. The other answer choices are incorrect because: A) 760.0 mb is the standard atmospheric pressure in millimeters of mercury, not millibars. B) 938.9 mb is not a standard atmospheric pressure value. C) 1000.0 mb is not the standard atmospheric pressure at sea level.
