Step 1: Concept Overview:
The question requires identifying accurate statements about Existentialism, a significant philosophical and literary movement of the 20th century.
Step 2: Detailed Analysis:
Evaluating each statement:
\[\begin{array}{rl} \bullet & \text{(A) Focuses on radical individual freedom. CORRECT. Existentialism's core idea, "existence precedes essence," posits that individuals are born without a predetermined purpose and must define their lives through choices, emphasizing freedom and responsibility. } \\ \bullet & \text{(B) Albert Camus and Jean-Paul Sartre are associated thinkers/writers. CORRECT. Jean-Paul Sartre is a leading figure in existentialism. Albert Camus, though he resisted the label, is a key figure whose works (e.g., The Myth of Sisyphus) are foundational for exploring existential themes. } \\ \bullet & \text{(C) The absurdity of human existence is a major theme. CORRECT. Existentialists, especially Camus, explore the "absurd" – the conflict between humanity's search for meaning and the inability to find it in a meaningless universe. } \\ \bullet & \text{(D) Its immediate inspiration was the French Revolution. INCORRECT. Existentialism originates in 19th-century philosophers like Kierkegaard and Nietzsche, flourishing post-World Wars amid disillusionment and questioning of values. The French Revolution (1789) predates it significantly. } \\ \end{array}\]Therefore, statements (A), (B), and (C) are correct.
Step 3: Conclusion:
The correct answer is (A).
