AI Explanation

The correct answer is A) 29.92 inches of mercury. The standard atmospheric pressure measured in inches of mercury is 29.92 inches. This is a well-established physical constant that is commonly used as a reference for atmospheric pressure measurements. The value of 29.92 inches of mercury corresponds to the average sea-level atmospheric pressure at 0 degrees Celsius or 32 degrees Fahrenheit. The other options are incorrect because: B) 500.0 inches of mercury is an unrealistic value for standard atmospheric pressure. C) 760.0 inches of mercury is the standard atmospheric pressure measured in millimeters of mercury, not inches. D) 1013.2 inches of mercury is the standard atmospheric pressure measured in hectopascals, not inches of mercury.
