Answer
C. a circuit.
Explanation
This question involves basic electricity fundamentals. Specifically, it’s referring to an electrical circuit. A cell connected to a lamp using wires forms an electrical closed-path configuration called a circuit. Electrical circuits are formed when a circuit loop allows electrical current to flaw between two points. Here, the battery (cell) supplies the electrical energy required, the wires act as the pathways to transfer this electric energy from the cell to the lamp causing it to light up. A circuit is usually composed of three basic components - an energy source (battery or cell), load (lamp), and conducting path (wires). Options such as a magnet, a turbine, and a dynamo are incorrect as they do not create electrical circuits; neither does a force or generator in the context of this question.
