The correct option is C Safranin
Safranin stains epidermal peel of leaf pinkish red in colour. Safranin is a biological stain used in histology and cytology. Safranin is used as a counterstain in some staining protocols, colouring all cell nuclei red. It can also be used for the detection of cartilage, mucin and mast cell granules.
Hence C is the correct option.
