C

Explanation:
Frederick Taylor is widely recognized as the founder of scientific management, a theory that emphasizes the systematic study of tasks, time management, and worker efficiency to improve productivity. Option A, the classical school of management, is broader and includes other contributors like Henri Fayol. Option B, specialization, is a concept associated with division of labor but not specifically tied to Taylor’s work. Option D, bureaucracy, is more closely linked to Max Weber’s theories. Therefore, C is the correct answer.
