    A)  Metal                                                           

    B)         Ceramic                

    C)                                        Clear plastic sheet

    D)         Frosted glass.                                        

    Correct Answer: C

    Solution :

    Metal and ceramic are opaque materials, hence cast a shadow when light rays fall on them. Frosted glass is translucent hence it does not allow all light rays to pass through it hence, it also casts a light shadow. Transparent materials like clear plastic sheet allow all the light to pass through them and do not cast a shadow.
