Explanation:

Step1: Recall Ohm's Law

According to Ohm's Law $V = IR$, where $V$ is voltage, $I$ is current and $R$ is resistance. A non - zero voltage drop ($V = 7.38V$) indicates the presence of resistance in the path between the ignition switch and terminal 86.

Step2: Analyze circuit fault location

The fault could be in the control circuit (the path from the ignition switch to the relay) rather than just the main circuit. There is no indication that the rear defroster element is related to this voltage - drop measurement. Also, a normal voltage drop from the ignition switch to 86 should be close to 0V in an ideal situation with no significant resistance in the wire.

Answer:

The statement "There is a resistance in the wire between the ignition switch and the relay (86)" is correct. The other statements "The fault can only be in the main circuit", "The rear defroster element is broken and requires repair or replacement", and "The voltage drop from the ignition switch to 86 should normally be 7.38 V" are incorrect.
