In the relationship between horsepower and watts, which option is correct?

Explanation:
Power is the rate of doing work, and horsepower is a traditional unit used for engines, while watts are the SI unit. The mechanical definition ties horsepower to a precise rate of work: 1 horsepower equals 550 foot-pounds of work every second. When you convert that to watts, you get about 745.7 watts, which is commonly rounded to 746 watts. So the correct choice reflects this standard conversion: 1 hp ≈ 746 W. The other numbers don’t match the conversion (1,000 W is about 1.34 hp, and the others are around 4 hp), so they’re not the right equivalent.
