mmmm is more of Ca BILIRUBINATE due to excessive bilirubin production and precipitation due to prolonged haemolysis. So is mainly BILIRUBIN stones and not cholesterol

The correct answer is A.
Bilirubin is a degradative product of hemoglobin metabolism. Bilirubin (pigment) stones are specifically associated with excessive bilirubin production in hemolytic anemias, including sickle cell anemia. Bilirubin stones can also be seen in hepatic cirrhosis and liver fluke infestation.
Calcium oxalate stones (choice B) and cystine stones (choice E) are found in the kidney, rather than the gallbladder.
Pure cholesterol stones (choice C) are less common than mixed gallstones, but have the same risk factors, including obesity and multiple pregnancies.
Mixed stones (choice D) are the common "garden variety" gallstones, found especially in obese, middle aged patients, with a female predominance.
