A saline enema is composed of salt and water. This solution is used to cleanse the colon, typically for medical or digestive health reasons. Option A, a detergent solution, is often used in enemas for bowel preparation before medical procedures, but it is not the same as a saline enema. Option B, a herbal infusion, is not a common ingredient in enemas, and would not be considered a saline enema. Option C, oil and water, is sometimes used in enemas for constipation relief, but it is not the typical composition of a saline enema. Therefore, option D, salt and water, is the most accurate composition for a saline enema.
