c) low resistance and low melting point.
We connect the fuse element in series with the voltage source in the AC or DC circuit. Or, it is connected in series with the appliance. So its resistance should be very low not to dissipate energy and alter current in the circuit.
We want that when excess current flows through the fuse, the increase in temperature should melt the fuse wire and then the circuit be broken. So its melting point should be low.
