A house-owner replaces a failed fuse for the lights of the house. When the lights are switched on, the second fuse also fails. The house-owner then uses a third fuse with a higher rating than the previous two. Why is this not a sensible thing to do?

• A. Fuses only allow the circuit to work if the rating is exactly right.
• B. The third fuse will melt because the rating is too high.
• C. Using a fuse with too high rating cause?s electric shocks.
• D. The circuit may work, but the fault is not corrected.
