• B. mol
• C. L
• D. atm

Answer: (D)

Verified step by step guidance

1. Understand that pressure is defined as force applied per unit area. Therefore, units of pressure must reflect this relationship.
2. Recognize that 'kg' (kilogram) is a unit of mass, not pressure.
3. Know that 'mol' (mole) is a unit used to count the number of particles or amount of substance, not pressure.
4. Identify that 'L' (liter) is a unit of volume, which is not used to measure pressure.
5. Recall that 'atm' (atmosphere) is a common unit of pressure, representing the pressure exerted by the Earth's atmosphere at sea level.
