Solution

The correct option is A charged particles
When an application of high voltage is provided to the electrodes, the neon gas ionizes due to the flow of $e^{-}$ which thereby excite the neon gas atoms and cause them to emit light. In the case of fluorescent tubes, low-pressure mercury vapour is present which emits UV light when ionized.
