Solution

The correct option is C Rocella tinetoria
The species of the lichen Rocella tinetoria is used for the extraction of the blue dye which serves in the formation of litmus. The litmus papers are used for testing of the pH. The litmus paper turns blue at alkaline pH and red at acidic pH. The change in the pH can be analysed using the litmus papers.
Thus, the correct answer is option C.
