Solution

The correct options are
C Object A is an opaque object.
D Object B is a transparent object.
Objects that do not allow the light to pass through them are called opaque objects. These objects form shadows. Object A forms shadow, so, it is an opaque object. Objects that allow the light to pass through them are called transparent objects. These objects do not form shadows. Object B does not form shadow so, it is a transparent object.
