Answer:
circuit is complete
Step-by-step explanation:
The correct statement that describes one feature of a closed circuit is:
a. the circuit is complete.
A closed circuit is one in which the current flows in a loop from a power source through wires, devices, and back to the source. In a closed circuit, the circuit is complete, meaning that there are no gaps or breaks in the circuit that would prevent the flow of current.
When a circuit is open (or broken), the current cannot flow, and the devices connected to the circuit will not work. Therefore, options (b), (c), and (d) are not features of a closed circuit.
