Solution

The correct option is D Absolute pressure = Atmospheric pressure + Gauge pressure
Absolute pressure: It uses absolute zero (pressure in vacuum) as its zero point.
Gauge pressure: It uses atmospheric pressure as its zero point.
Therefore, Absolute pressure = Atmospheric pressure + Gauge pressure
