I don't think we can form Chylomicrons if we inhibit the absorbtion of fats from the GI?
(D --> Synthesis of cholesterol in the liver can still occur. Because they're made from Acetyl-CoA, which can be derived from Glucose. So even if we inhibit the absorption of fats, cholesterol synthesis can still occur)
My guess.

its a resin that complexes bile salts and prevents their reabsorption from GI tract. so I guess C is the right ans.
