(B) Joules per second

Power is the amount of work done per unit of time. Since work is measured in Joules, the SI unit of power is Joules per second (J/s), or Watts (W).
Of course, the cooler unit of power is the Horsepower (hp), originally introduced by James Watt himself, using which people nowadays still boast about their favorite car's "strength."
