The correct answer is B) Figure "A" is a wiring diagram and figure "B" is a ladder or line diagram (schematic). This is correct because a wiring diagram, such as figure "A", shows the physical connections between components using symbols, while a ladder or line diagram (schematic), such as figure "B", depicts the circuit in a more simplified, schematic form using standard electrical symbols. The wiring diagram provides a visual representation of the actual physical layout, while the ladder diagram focuses on the logical flow and interconnections of the electrical system. The other options are incorrect because they do not accurately describe the relationship between the two types of electrical diagrams shown in the illustration.
