A
Correct answer
Explanation
Power is measured in watts (W) or kilowatts (kW) - kilowatt is commonly used for larger power values. Pressure is force per unit area, measured in N/m² (Pascals) or equivalently kg/m·s². Energy is measured in joules, but kilowatt-hour (kWh) is also a practical unit. Radioactivity is measured in becquerels (Bq), representing one nuclear decay per second.
