Which text is frequently described as the 'Tamil Veda'?

Nalayira Divyaprabandham

The correct answer is Option (2) → Nalayira Divyaprabandham

The importance of the traditions of the Alvars and Nayanars was sometimes indicated by the claim that their compositions were as important as the Vedas. For instance, one of the major anthologies of compositions by the Alvars, the Nalayira Divyaprabandham, was frequently described as the Tamil Veda, thus claiming that the text was as significant as the four Vedas in Sanskrit that were cherished by the Brahmanas.
