The correct answer is C: Buddhist. Taxila, an ancient city located in modern-day Pakistan, was a pre-eminent center of learning and culture, particularly associated with Buddhist civilization. During the Gandhara period, from roughly the 6th century BCE to the 11th century CE, Taxila flourished as a major hub for Buddhist monasteries, stupas, and universities. It attracted scholars and students from across Asia and played a crucial role in the dissemination of Buddhist thought and art, evident in its numerous archaeological ruins and artifacts.
Option A: Hindu is incorrect. While Hindu traditions have ancient roots in the Indian subcontinent, and Taxila existed during periods when Hindu influences were present, its most celebrated and historically significant association as a learning center is with Buddhism. Many Hindu texts were also studied, but Buddhist institutions were paramount.
Option B: Sikhism is incorrect. Sikhism is a religion that originated in the Punjab region of India in the 15th century CE, much later than Taxila's peak as an ancient city. Its historical and religious centers are in different locations.
Option D: Aryan is incorrect. The Aryan civilization refers to the Indo-Aryan culture that established Vedic traditions in the Indian subcontinent, predating the rise of Buddhism and Taxila's peak as a Buddhist center. While Taxila existed during the broader historical timeline, its specific fame is not primarily tied to the Aryan civilization.
