As shown in figure "1" of the illustration, a correctly connected synchronous transmission causes the receiver to be in correspondence with the transmitter. If the receiver is out of correspondence, 180 degrees out of zero, but the torque direction is correct as shown in figure "2", what figure shows the incorrect connections responsible for this condition?

Correct Answer: Option C — B
Synchronous data transmission loops rely on specific phase relationships between stator and rotor windings. Reversing excitation or signal leads alters torque vectors, and figure B depicts the specific erroneous terminal cross-connections that maintain correct rotational torque direction while leaving the receiver 180 degrees out of phase from true correspondence.
