Answer: A

Explanation: When a battery, wire, and lightbulb are connected in a straight line (in a complete circuit), the battery provides electrical power, and the lightbulb illuminates. The electrical current flows from the battery through the wire, passes through the filament in the lightbulb, and then returns to the battery, completing the circuit and allowing the lightbulb to function
