The correct option is B I - Opaque
II - Translucent
III - Transparent
In I, we are not able to see the body of the giraffe. It means it does not allow light to pass through. It's opaque.
In II, we are able to see the body, but not clearly. We call such objects translucent.
In III, we are able to see the body very clearly. This object allows light to pass through completely. We call such objects transparent.
