What treatment options are available for gallstones?

B is the correct answer because the treatment options for gallstones can vary depending on the severity of symptoms, the size and type of the stones, and other individual patient factors.

Grapefruit juice and certain medications can help manage gallstones and alleviate symptoms; for example, medications such as ursodeoxycholic acid are sometimes used to dissolve cholesterol gallstones. However, if gallstones cause significant pain or complications like infection or pancreatitis, surgical intervention, particularly cholecystectomy (the surgical removal of the gallbladder), is often necessary. This combined approach of using dietary modifications, medications, and, when necessary, surgery provides a comprehensive management strategy for patients dealing with gallstones.

Other options presented, such as dietary changes alone, do play a role in managing gallstone issues by potentially preventing the formation of new stones, but they are insufficient as standalone treatments in many cases. Antibiotics might be used if an infection is present, but they do not treat the stones directly. Physical therapy is not relevant to the treatment of gallstones.
