• A. Series Circuit
• B. Parallel Circuit
• C. Mixed Circuit
• D. Combination Circuit

Answer: (D)

A circuit with both series and parallel parts shows how current and voltage distribute differently in the two ways they can connect components. In a series path, the current is the same through every component and the voltages add up; in parallel branches, the voltage across each branch is the same and the currents split among branches. When a circuit contains both patterns, you analyze it by identifying series blocks and parallel blocks and replacing each block with its equivalent resistance, then reducing step by step until you have a single equivalent resistance. From there, you use Ohm’s law to relate total current, total voltage, and the resistances. This blending of configurations is exactly what a combination (or mixed) circuit describes, but the standard term that clearly conveys the presence of both arrangements is combination circuit. The reason the other descriptions don’t fit as well is that they imply only one arrangement, either all in series or all in parallel, which wouldn’t capture the mixed structure of the circuit.
