B Correct answer
Explanation

William Harvey discovered the circulation of blood in 1628 through his work 'De Motu Cordis' (On the Motion of the Heart and Blood). He demonstrated that blood flows in a continuous circuit through the body, pumped by the heart. Darwin is associated with evolution, Aristotle with early biological classification (but not circulation), and Lister with antiseptic surgery. This is a foundational discovery in physiology and medicine.
