• A. Pictorial
• B. Block
• C. Schematic
• D. Flow diagram

Answer: (C)

Electrical diagrams use standardized symbols to represent devices and show how they’re connected. That style is a schematic diagram. It focuses on circuit relationships and operation, not the exact physical layout, so technicians can trace paths and analyze circuits logically. A pictorial diagram aims to resemble the actual appearance of the equipment, making recognition easier but not detailing precise connections. A block diagram shows functional blocks and the flow between them without wiring at the component level. A flow diagram maps steps or processes rather than electrical interconnections. Therefore, the diagram described is a schematic.
