Solution

The correct option is B
Decrease

Now if the air is gradually removed from the Jar, it will lower down the atmospheric pressure which in turn is simply the weight of air molecules contained above the liquid surface.

As $P_{T o t a l} = P_{a t m} + ρ g h$

$P_{T o t a l}$ gradually decreases
