    Wonder whether you may expect us to answer your question without the aid of a sketch

    as shown in figure ???

    unable to answer without that..  but hard to imagine any answer except C, as electricity travels very fast, close to the speed of light. But there is a significant time for them to warm up to reach the temperature at which light is emitted, and how fast they warm up depends on a lot of factors, bulb size, rating, shape, current etc.

    I suspect even with the drawing, this is one of those idiotic questions from a teacher without a good knowledge of physics.

    for example, a 120 volt rated bulb with 12 volts applied will not glow at all.
