Answer: 3.

Explanation:

Both red and blue litmus papers are changing color in acid and the main use of them is to test whether a solution is basic or acidic.

Under acidic conditions, blue litmus paper will turn red, and red litmus paper will turn blue under basic conditions.

Purple litmus paper is always neutral which means that blue and red will always be purple in neutral environment.
