Medieval Indian classical musicians

Statement 1 is incorrect - Tyagaraja's kritis are primarily devotional songs in praise of Lord Rama, not Krishna. Statement 2 is correct - Tyagaraja indeed created and composed several new ragas, contributing significantly to Carnatic music theory. Statement 3 is incorrect - Annamacharya (1426-1535) lived centuries before Tyagaraja (1759-1847), so they cannot be contemporaries. Statement 4 is correct - Annamacharya's kirtanas (devotional compositions) are indeed in praise of Lord Venkateshwara of Tirupati. Therefore, only statements 2 and 4 are correct. > Key distinction: Tyagaraja = Rama devotion + raga creation; Annamacharya = Venkateshwara devotion + earlier period. Answer: (b).
