Step 1: Understanding the Concept:
The question asks about the primary role of Aung San Suu Kyi in the context of her life and achievements.
Step 2: Detailed Explanation:
Aung San Suu Kyi is internationally known for her long struggle for democracy and human rights in Burma (Myanmar). However, beyond her activism, she also formally entered the political arena as the leader of the National League for Democracy (NLD).
Her political career, leadership, and recognition as a stateswoman define her most accurately as a Burmese politician. While activism was central to her rise, her lasting role in her country's history is tied to her political leadership.
Options (C) and (D) are irrelevant, and option (B), though partly true, is less precise in this exam context.
Step 3: Final Answer:
Aung San Suu Kyi is a Burmese politician.
