Who amongst the following was one of the main proponents of Neo-Vaishnava sect in Assam during the 15th century?

The Neo-Vaishnavite movement in Assam was started by Srimanta Sankardev, a scholar, poet playwright & social-religious reformer. This movement played an important role in constructing the medieval Assam. It transcended deep into the fabric of the Assamese society overcoming all barriers of caste, creed and religion. The ideas and philosophy of Sankaradeva became an integral part of the life of locals. The religious institutions like Namghars (prayer hall) and Satras (monasteries), which were built to spread the Bhakti movement, had a big influence in the political & social life of the people. These institutions worked as a community centre for the masses.
