(a).
(b).
Explanation:
Absolute pressure = gauge pressure + atmospheric pressure.
"Gauge Pressure" is the pressure due the liquid alone. This is given by:
=
To get the absolute pressure we need to add on the pressure due to the weight of the air above it. We add on the atmospheric pressure which I will assume to be
Absolute pressure
