The correct answer is Michel Foucault because "biopower" is a concept developed by him. Let me explain.
What is Biopower?
Biopower refers to the way modern states regulate their citizens through an array of institutions, norms, and practices that manage life. It focuses on the administration of bodies and the management of populations, especially concerning issues like public health, reproduction, sexuality, and surveillance.
Foucault introduced the idea in his works "The History of Sexuality" and "Discipline and Punish". He argued that, in modern societies, power is not just enforced through force or coercion (like in traditional authoritarian systems) but through more subtle means such as the medical system, education, laws, and various forms of knowledge.
Why the Other Options Are Incorrect:
Edward Said – Known for his concept of Orientalism, analyzing how the West constructs knowledge about the East.
Chinua Achebe – A Nigerian novelist famous for "Things Fall Apart", focusing on African post-colonialism.
Walter Benjamin – A philosopher and critic known for his essays on aura, art, and history, not biopower.
