If a solution turns red litmus blue and turmeric reddish brown, what is its nature?

Answer and explanation

Correct answer: Basic

A base changes red litmus paper to blue because the solution provides a basic medium. Turmeric is also a natural indicator: it turns reddish brown in the presence of a base, while it generally remains yellow in acidic or neutral conditions. Since both independent tests indicate alkalinity, option B is correct. An acidic or neutral solution would not produce both changes, and being salty does not automatically mean that a solution is neutral.
