Solution
The correct option is D Faulty circuit design
A Miniature Circuit Breaker(MCB) is an electromechanical device that protects the electric circuit from large currents which may result in case of an overloading or short circuit or even any improper faulty circuit design. Overloading happens when the appliances used in the household circuit draw a heavy amount of current from the main supply that exceeds the operation limit of the MCB.
