(b) decrease
EXPLANATION:
The pressure at the bottom of the liquid is the sum of atmospheric pressure and the pressure due to the height of the liquid. When the air inside the jar is continuously pumped out the pressure of the air part decreases. Hence the total pressure at the bottom of the liquid will decrease.
