Solution

The correct option is A Statement 1 is correct and statement 2 is incorrect
During short circuit, wires come in direct contact and a large amount of current flows through the circuit. Therefore statement 1 is true.

In case of overloading, many devices are connected to the same circuit. So, a large amount of current flows through the circuit.
Therefore, statement 2 is false.
