During chemistry lab, one lab group decomposes potassium chlorate to collect oxygen gas by water displacement. The total volume is 220 milliliters and is collected at a pressure of 101 kPa at 24°C. The vapor pressure of water at 24°C is found to be 2.98 kPa.

What is the pressure of the oxygen collected?
A 104.28 kPa
B 101.20 kPa
C 98.2 kPa
D 98.02 kPa
