Material.
Explanation:
Eddy currents are circular currents induced in a conductor when it is subjected to a changing magnetic field. In an eddy current damping system, a conducting disc is placed in a magnetic field. When the disc is displaced, eddy currents are induced in the disc, which in turn generate a magnetic field that opposes the original magnetic field. This produces a damping effect that slows down the motion of the disc.
Therefore, the disc employed in an eddy current damping system should be made of a conducting material to allow for the induction of eddy currents. Materials such as copper, aluminum, and brass are commonly used for this purpose.

In the eddy current damping the disc is suspended freely between the permanent magnet. As disc is connected to pointer and spindle. It will rotate when the meter is used to show an reading . Thus when the disc roatate in the magnetic field as the disc is made up of condicting material it will induce some current by the principal of faradays law. This will slow down the speed of pointer and help in the damping.
Do the ans is B
P.s: if mangetic material is used to manufacture the disc the disc will get locked between the permanent magnet in such direction that maximum flux can flow due to which pointer will not move and meter cannot indicate the reading
