A student touches the metal body of a refrigerator whose live conductor has come loose and is touching the body. The refrigerator is properly earthed. What is most likely to occur?
a) The student receives a severe electric shock because the body provides the only path for current
b) A large current flows to ground through the earth wire, the fuse blows instantly, and the student is protected
c) Only a small leakage current passes through the student while the refrigerator continues to operate
d) The fault current returns through the neutral wire, so the circuit keeps working without any interruption
