Step 1: Identify the Alvar saints.
The Alvars were Tamil poet-saints devoted to Vishnu, who composed devotional hymns during the Bhakti movement in South India.
Step 2: Their composition.
The collective hymns of the Alvars were compiled as the Nalayira Divyaprabandham, meaning “Four Thousand Divine Compositions.” These works are dedicated to Lord Vishnu and his avatars.
Step 3: Elimination.
- (A) Tevaram: A collection of Shaivite hymns composed by Nayanar saints, not by Alvars.
- (B) Nalayira Divyaprabandham: Correct, composed by Alvars.
- (C) Both (A) and (B): Incorrect, since Alvars only composed Divyaprabandham, not Tevaram.
- (D) None of these: Incorrect.
Step 4: Conclusion.
Therefore, the composition of the Alvar saints is the Nalayira Divyaprabandham.
