Answer: a. causes phelophtalein indicator to change from colorless to pink

Explanation:

Phenolphtalein is an indicator, which means it can visually change when given certain circumstances.

Phenolphtalein turns fuchsia when exposed to basic substances, especially above a pH of 8.2, due to ionization, which changes the structure of the indicator.
