Answer - A - When you connect the conductors of a wire pair to different pins of a terminator at each end of a cable, it is known as a reversed pair.

Key Takeaway: Reversed pair is a condition where two lines in a pair are connected to opposite pins at each end of the cable. It is called a polarity reversal, or tip-and-ring reversal. If there is a reversed pair condition, the signals on the telephone line would not be properly received or transmitted.
