The cause of a fire in a computer is described as an incorrectly wired circuit.

A
The wiring contained a short circuit, so the reduced resistance caused an increase in current.
B
The wiring contained an open circuit, so the reduced resistance caused an increase in current.
C
The wiring contained a closed circuit, so the current was redirected around the components that would have provided the proper resistance.
D
The wiring contained an open circuit, so the current was redirected around the components that would have provided the proper resistance.
