In a solution, blue litmus turns red and universal indicator shows red colour. What is the nature of the solution?

Answer and explanation

Correct answer: Acidic

Blue litmus turning red is the characteristic test for an acidic solution. The red colour of a universal indicator also corresponds to a low pH, generally indicating strong acidity rather than neutrality or basicity. A neutral solution would leave litmus unchanged and show a colour near pH 7, while a basic solution would turn red litmus blue. Therefore option A is correct.
