The answer is B.

The valvular disease is calcific aortic stenosis, a disease of the elderly in which nodules of calcium salts, notably calcium phosphate salts, form as a result of dystrophic calcification. Dystrophic calcification can also be seen at sites of previous necrosis of many etiologies (coagulative, caseous, liquefactive, or enzymatic fat necrosis) and in advanced atherosclerosis.

Calcium oxalates (choice A) are found in some kidney stones.

Complexed iron (choice C) is seen in hemosiderin depositions, often at sites where there has been previous hemorrhage or if there is a systemic overload of iron.

Magnesium phosphates (choice D) are found in some kidney stones.

Uric acid (choice E) and urate deposits can be seen in gout and some kidney stones.
