• A. Series circuit
• B. Parallel circuit
• C. Light bulb
• D. Battery

Answer: (A)

A circuit with only one path for current is called a series circuit. In a series circuit, the same current flows through every component because there’s just a single route for the charges to take. That means all elements are arranged in a single loop, and the total resistance is the sum of the individual resistances while the supply voltage is shared across the components. If any part of the path is interrupted, the entire circuit stops because there’s nowhere else for the current to go. The other terms listed—like a light bulb or a battery—describe a device or a power source, not the way the current paths are arranged.
