Answer

Brief Explanations:

To demonstrate that an electric current produces a magnetic field, we need a source of electric current (battery), a conductor to carry the current (coil of wire), and a device to detect the magnetic field (compass). A compass can show the presence of a magnetic field by deflecting its needle. Paper - clips, iron nails, and permanent magnets are not necessary for this basic demonstration.

Answer:

A. A battery, a coil of wire and a compass.
