The correct answer is:
C. Phase contrast microscopy
Phase contrast microscopy is commonly used for examining transparent and colorless objects phase contrast microscopy is a technique that allow a light to pass through a transparent specimen in order to form an image by manipulating the color reflection to our Retina.
Explanation:
The phase contrast microscope is generally used for monitoring such specimens as biological tissues. It is a variety of light microscopy that becomes contrasts of transparent and colorless objects by changing the optical path of light.Phase-contrast microscopy is an optical microscopy method that changes phase shifts in light moving through a crystalline specimen to brightness variations in the image.
