Solution

The correct option is C
Turmeric

Indicators are substances that help us to distinguish between acids and bases through colour change. Turmeric is an acid-base indicator. It remains yellow in acidic solutions and turns to red in basic solutions. Vinegar is acidic in nature whereas lime water and baking soda are basic in nature.
