Answer : The correct option is, (A)

Explanation :

At STP (standard temperature and pressure), the temperature is 273 K and pressure is 1 atm or 101 KPa.

Karen measures the volume of gas at 200 K and 100 KPa.

From this we conclude that the pressure of the gas are approximately equal. So, to correct her measurement to standard temperature and pressure (STP), she should make a volume correction based on a higher temperature of 273K.

Hence, the correct option is, (A) make a volume correction based on a higher temperature of 273 K
