14. Which of the following are important parameters in microscopy? A. Magnification B. Resolution C. Contrast D. All of the above

The correct answer is D. All of the above. Magnification refers to the size of the image compared to the actual size of the object being observed. Resolution is the ability of the microscope to distinguish two adjacent points as separate entities. Contrast is the difference in light intensity between the image and the background. All of these parameters are important in microscopy for obtaining clear and accurate images.
