What is called the rate of doing work in an electric circuit?

Charges carry some electrical energy with them when they move in an electric circuit. Work is done in the circuit when they travel from an area of higher to lower or lower to higher potential difference. The quantity of energy transferred and the duration of time that charges were in motion may be used to calculate the rate of work being done.
Mechanical power, which includes electric power, is the rate at which work is accomplished. It may also be described as the rate of electrical energy consumption per unit time. The pace at which energy is converted into an electrical circuit is referred to as electric power. It is a gauge of the amount of energy consumed in,

 Power $=\frac{\text{ Energy }}{\text{ time }}$
Electrical energy is given by,
$E=V Q$
Therefore,
$P=\frac{VQ}{t}$

V stands for volts of electric potential.
In Coulombs, Q represents electric charge.

The time in seconds is t.

Electricity or electrical power is simply the rate at which electrical energy or electricity is passed or transferred by an electric circuit, as measured in terms of time units. Different units can be used to measure power. One watt is equal to one joule per second and is the SI unit used to measure power.

Hence, the correct option is A.
