Best answer
Correct option is (a) Galvanometer

For explanation I would say: Faraday used a galvanometer and connected it to a coil. A bar magnet was pushed towards the coil, such that the north-pole is pointing towards the coil. As the bar magnet is shifted, the pointer in the galvanometer gets deflected, thus indicating the presence of current in the coil.
