Which of the following is a risk factor for deep vein thrombosis (DVT)?

Explanation:
Medications that change how easily blood clots form influence DVT risk. Estrogen-containing oral contraceptives create a procoagulant state by increasing the liver’s production of clotting factors and reducing natural anticoagulants, tipping the balance toward thrombosis in the deep veins. Regular exercise improves venous return and lowers risk, a normal body mass index is associated with reduced risk, and high calcium intake has no established link to DVT. So the oral contraceptives are the risk factor among the options.
