Solution

Explanation:
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.
Hence, option (C) is correct.
