Solution

The correct option is D Water remains colourless
Phenolphthalein is a laboratory indicator. It remains colourless when added to acidic or a neutral substance. But it turns to pink when added to basic substance. Since distilled water is a neutral compound, it remains colourless when phenolphthalein is added to it.
