Explanation:

Step1: Recall pressure conversion

Standard atmospheric pressure is 760 mmHg, and its equivalent in Pascals is a known value. We know that 1 atm (atmosphere) is equal to 760 mmHg, and also 1 atm = 101325 Pa.

Step2: Match with options

Given the pressure is 760 mmHg (which is 1 atm), converting to Pa gives 101325 Pa. Looking at the options, 101,325 Pa is the correct one.

Answer:

The correct option is the one with "101,325 Pa" (the third option in the list of radio buttons).
