Which substance can identify a basic solution as a natural indicator?

Answer and explanation

Correct answer: Turmeric

Turmeric contains the natural pigment curcumin, which acts as an acid-base indicator. It remains yellow in an acidic or neutral medium but changes to a reddish-brown colour in a basic medium, such as a soap solution. Therefore, turmeric in option A can identify a basic solution. Common salt, sugar, and pure water do not show this characteristic indicator colour change in the stated test.
