Which of the following concerns the transmission line protection using Distance Relay?

A. Arc resistance affects Mho Relay rather than Impedance Relay.
B. Power Swing will not affect the operation of the distance relay. Because the electrical system will return to its normal state If the system is large enough
C. When a fault occurs with and arc resistance will affect the operation of the Reactance Relay.
D. Distance relay is suitable for shielding the transmission line because it works very fast. Regardless of the type of fault or any position on the transmission line
