Solution
The correct option is A Diamond is a better reflector of light than graphite.
An object appears to shine more if more light rays from the object fall on our eyes. This phenomena can take place in two ways. First, if the object itself is a source of light i.e. a glowing bulb and second, if the object is an excellent reflector of light. Since, diamond is not a luminous body, it does not emit any light by itself. Each face of a diamond is a highly polished surface which facilitates considerably high reflection. Thus a diamond shines more than a graphite because diamond is a better reflector of light than graphite.
