Why is the fuse wire in a household circuit made of an alloy having a low melting point? (a) So that its resistance is negligible and it does not affect current flow (b) So that it can withstand voltage fluctuations without breaking (c) So that it quickly melts when the current exceeds the safe limit (d) So that it can carry very large current without heating
