Solution

The correct option is A
transfer the vibrations of the moving coil to the air

At the front of the moving coil loudspeaker, there is a cone or diaphragm. This transfers the vibrations of the moving coil to the air, presenting a large surface area. The loudspeaker diaphragm can be made of fabric, plastic, paper, or lightweight metal.

Which component of a moving coil loudspeaker vibrates to produce sound?

Moving coil galvanometer operates on Permanent Magnet Moving Coil (PMMC) mechanism.

Moving coil galvanometers are of two types
(a) Suspended coll
(b) Pivoted coil type or tangent galvanometer,

Its working is based on the fact that when a current carrying coil is placed in a magnetic field, it experiences a torque. This torque tends to rotate the coil about its axis of suspension in such a way that the magnetic flux passing through the coil is maximum.
