Which of the following statements about kilowatts and horsepower is true?

• A. 0.67 amperes at voltage of 120
• B. 746 watts
• C. 1.34 horsepower
• D. 1000 megacycles

Answer: (C)

When you compare kilowatts and horsepower, use the direct conversion: 1 kilowatt is about 1.341 horsepower. Since 1 kW equals 1000 watts and 1 HP is about 745.7 watts, 1000 / 745.7 ≈ 1.341 HP. So a statement saying 1.34 horsepower corresponds to about 1 kilowatt, which makes that option true.

The other choices don’t reflect this power-unit relationship. The first option uses current and voltage to state a power in watts, not a kilowatt-to-horsepower relationship. The frequency option is about cycles per second, not power. The remaining wattage option is essentially another way to express horsepower in watts, but the direct kilowatt-to-horsepower conversion is the key relationship being tested.
