Answer

Correct answer: b) Thromboembolism

Estrogen in combined oral contraceptives increases hepatic synthesis of several clotting factors, raising the risk of venous thromboembolism — the most clinically significant and most commonly cited adverse effect of long-term OCP use, particularly in smokers over 35 years. Cataract, hypothyroidism, and hyperkalemia are not characteristic OCP adverse effects.
