In an experiment to measure the pH values of solutions, a student placed strips of universal indicator paper in four beakers containing solutions A, B, C and D. The colour of universal indicator paper in these solutions is as shown below :

The solution having lowest pH value is:
(1) A
(2) B
(3) C
(4) D
