There is said to be a short circuit when one part of a parallel circuit has a very low resistance and almost all the current will flow through this part and very little current will flow through the other part.
What is short circuit?
Short circuit means when a normal wire comes in direct contact with another wire, then the resisitance value turns zero and flow of current is ebruptly increases.
So, if in any wire very little or no resistance is present and high amount of current will flow from that wire then in this case short circuit occur. It generally occurs in the parallel circuit because in the closed circuit that much of current flow is not present that cause short circuit.
Hence option (B) is correct.
