Final answer:
Lugol's solution is used for staining cells in biological studies to better visualize cell structures. It reacts with starches in cells, highlighting them under a microscope. It is not used for medical treatments or nutritional deficiencies.Answer is OPTION C
Step-by-step explanation:
Lugol's solution is commonly used for staining cells in biology, particularly when examining and identifying cellular components under a microscope.
This iodine-based solution is known for its ability to bind to starches in cells, which results in a color change and allows for better visualization of cell structures, such as the nucleus, amyloplasts, and other organelles that contain starch. It is not used for treating vitamin C deficiency, disinfecting wounds, or preventing potassium deficiency.
