Best answer
The correct option is (c) 5W

The best I can explain: Electrical power is the rate at which electrical energy is converted to another form, such as motion, heat, or an electromagnetic field.

Power, P = V x I. By substituting the values of voltage(V) and current(I), we have P = (5×10^3)(1000×10^-6) = 5W.
