The correct option is
D stone
- Transparent Medium allows most of the light energy to pass through it. For example glass, diamond, air, vacuum.
- Translucent Medium partially allows the light energy to pass through it. For example, ground glass, muddy water, smoke, dust-filled air.
- Opaque Bodies do not allow light energy to pass through them. For example, bricks, stones, wood.
Hence, option (d) is correct.
