Solution
The correct option is A Fuse 1
From the given circuit, the path A has only one fuse (1) while the path B has a bulb and a fuse (2). So path A will have lesser obstruction to the flow of current than path B and current in path A will be higher. So the fuse 1 will blow up first after the switch is closed.
