Solution

Correct Option: 4

One metric horsepower equals approximately 735.5 watts, commonly rounded to 736 W. (The mechanical/imperial horsepower is about 745.7 W, rounded to 746 W.) The NTA key accepts 736 W.

Note: Both 736 W (metric HP) and 746 W (mechanical HP) are defensible depending on convention. We have followed the NTA key.
