Standard temperature and pressure, or STP, is defined as 0°C (273.15 K) and 1 atm (101.325 kPa). Option A, 0°C and 1 atm, matches these criteria. Option B, 0°F and 1 atm, is not a standard unit for temperature measurement and option C, 0 K and 1 atm, is incorrect because at 0 K, all matter is in a state of absolute zero and there can be no gas pressure.
