Question

Accepted Answer

In a conducting wire, current is driven by electric field , which points in the direction of current flow . Since the wire is bent into a loop, current must keep moving forward along the curved path. This means the electric field is tangential to the wire at each point to maintain the flow.    A Electric field cannot be zero  otherwise, current wouldnt flow.   B If potential difference were same between any two points, current would not flow .   C Electric field inside the conductor is tangential to the wire at all points, driving current around the loop.   D A symmetric loop can sustain current  symmetry doesnt prevent flow.   Therefore, the correct answer is option c.
