Power is the energy consumed to do work in unit time. It is calculated by dividing the work done with the time it took for the work to be done. It is expressed as:

Power = Work / Time = Force x Distance / Time
Power = 160 N (1 m) / 0.5 s = 320 W

Therefore, the correct answer is the third option. 

Hope this answers the question. Have a nice day.
