Solution

The correct option is C
pH 7

pH paper is used to examine whether a substance is acidic or alkaline. The colour change produced when a pH paper is dipped in a solution is compared with the colour chart to find whether the solution is acidic or alkaline in nature. The diagram given below shows the pH chart along with colour of the pH paper:

As seen in the chart, the pH paper turns light green if the pH value of the solution is 7.
