  • D. Neither A or B
Schematic diagram of an alternator circuit.

17.

Answer A is wrong. Vehicle manufacturers create diagrams of the entire vehicle that can be complex and difficult to sort through, so they're broken down into system-specific diagrams called block diagrams.

Answer B is wrong. Schematics are used in electronics; they contain standardized symbols to represent components in a circuit. The diagram above contains 12 diodes and 4 resistors.

Answer C is correct. Both A and B are correct.

Answer D is wrong. Both A and B are correct. The schematic contains diodes, resistors, a variable resistor, and symbols representing solid-state circuitry.
