Solution

The correct option is C
Device 'X' is a concave mirror of focal length 12 cm

Because the light rays coming from infinity get reflected by the device 'X' and converge at a point at a distance 12 cm from it, the device 'X' is a concave mirror of focal length 12 cm.
Hence, the correct option is C.
