Correct answer: D
Explanation
The correct answer is option 4 i.e. James Watt.
The term 'horsepower' was first used by James Watt. He coined this term in the late 18th century to help compare the power of steam engines with the work done by horses. Watt wanted to show the efficiency of steam engines in performing tasks traditionally done by horses. By equating the engine's power to that of a horse, he helped promote the use of steam engines in industry. This concept eventually became a standard unit of power measurement.
