Solution

The correct option is B not glow
Non-electrolytes are the solutions that do not conduct electricity or allow the movement of charged particles through them. So if the bulb is connected to a cell via electrodes immersed in a non-electrolyte solution, the bulb does not glow because the charges cannot move.
