Solution
The correct option is A
Electric current is the flow of electric charge (electrons). Electric current will only flow in a circuit when:
(i) It is complete i.e it has a closed path.
(ii) It has at least one source of power (electric cell).
(iii) Connections are properly made.
When the wires are connected to the same terminal of the battery, then no current will flow through the wires, and the bulb will not glow.
