Litmus paper can come in both red and blue. If Litmus paper turns blue, then it indicates that the solution is a base, whereas red indicates that the solution is an acid. If you dip a blue piece of litmus paper into a basic solution, it will remain blue. The same goes for placing a red piece of litmus paper in an acidic solution - it would stay red. So, your answer would be A.
