Option 1 -> (C), (A), (B), (D) - Panini → Buddhist texts → Ayurvedic texts → Natyashastra - follows correct chronological sequence.
Option 2 -> (C), (B), (A), (D) - Places Charaka-Sushruta before Buddhist texts, which is incorrect.
Option 3 -> (B), (A), (D), (C) - Places Ayurvedic texts first and Panini last, which is chronologically wrong.
Option 4 -> (B), (D), (A), (C) - Completely inverted order, placing Panini at the end instead of beginning.
Hence, Option 1: (C), (A), (B), (D) -> The correct chronological sequence is: Ashtadhyayi of Panini (4th century BCE), Early Buddhist texts/Tripitaka (5th-3rd century BCE compilation), Charaka and Sushruta Samhitas (2nd century BCE-2nd century CE), and Natyashastra of Bharata (200 BCE-200 CE). Panini's grammar predates Buddha's teachings, Buddhist texts were compiled after Buddha's death, followed by the systematization of Ayurvedic knowledge and later the codification of dramatic arts. -> correct
