We know that electric power is given by P = VI … (i)

**So, the option (c) is correct.**

According to Ohm’s law, V = IR … (ii)

Now putting the value of V from (ii) in (i), we get

Power P = (IR) × I = I^{2}R

**So, the option (a) is correct.**

Now putting the value of I from (ii) in (i), we get

Power P = V(V/R) = V^{2}/R

**So, the option (d) is correct.**

**Hence, the option (b) does not represent electrical power in a circuit.**
