The correct options are
B Fluoroscent bulb
C Paper dipped in oil
D Blue coloured glass
Any object which partially allows light to pass through it is a translucent object, whereas the one that allows light to completely pass through, is transparent. Here, bulb and glass could no more be transparent once they are painted, as after painting, only some light can pass through them, hence making them translucent. Also paper dipped in oil is a translucent object.
However, a piece of white chalk is an opaque object and hence, light cannot pass through it.
