Answer - C - The characteristic of a cable where a signal in one channel leaks into another channel and distorts the signal is called Crosstalk.

Key Takeaway: Crosstalk is a disturbance caused by the electric or magnetic fields in one communication channel affecting a signal in an adjacent channel. The phenomenon that causes crosstalk is called electromagnetic interference, or EMI. It can occur in microcircuits within computers and audio equipment, as well as within network circuits. The term is also applied to optical signals that interfere with each other. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one channel to another.
