A and C both are the correct answer.
If we measure absolute pressure above the atmospheric then option A.
and below the atmospheric pressure then C.
If we measure absolute pressure above the atmospheric then option A.
and below the atmospheric pressure then C.

Absolute pressure is zero reference against a perfect vacuum so it is = Gauge pressure + atmospheric pressure.
Similarly the Gauge pressure is zero reference against a atmospheric pressure.
Similarly the Gauge pressure is zero reference against a atmospheric pressure.

Gauge pressure = Absolute pressure - Atmospheric pressure.
From this we get answer.
From this we get answer.

The fluid in the gauge exerts a pressure in opposite direction which is atm pressure.
That's why the gauge pressure shown is less than the absolute pressure.
That diff is atm pressure.
That's why the gauge pressure shown is less than the absolute pressure.
That diff is atm pressure.
