Explanation:

Horsepower is a unit of power. James Watt determined that 1 horsepower is the power needed to lift 75 kilograms by 1 meter in 1 second (considering gravitational force and work - power relationships). The other options (100 kg and 1 kg) do not align with the established definition of 1 horsepower.
