The correct answer is Option D.
Explanation:
Power is defined as the amount of work done in a unit time.
Mathematically,
![Power=\frac{W}{t}](/tpl/images/0188/7060/9e43d.png)
S.I. Unit for power is Watt and other units that are used to measure power are horsepower, ergs/sec, Joules/ sec and many more.
Power is also defined as the product of force and velocity. Mathematically,
![Power=F.v](/tpl/images/0188/7060/e7678.png)
The units for this equation or power will be N.m/s (Newtons. meter per second)
Hence, the correct answer is Option D.
