Which one of the following statements with regard to the Moidams, built by the Tai-Ahom kingdom and inscribed as a World Heritage Site by UNESCO, is/are correct? 1. They acted as army fortresses. 2. They were recreation centres of the Royals and Nobles. 3. They were burial grounds of the Royals and Nobles. 4. They were battle drill centres of the Royals and Nobles. Select the answer using the code given below:

Moidams (Maidams) are the mound-burial system of the Tai-Ahom dynasty that ruled Assam for nearly 600 years (13th–19th century). They are essentially royal burial mounds where Ahom kings, queens, and nobles were buried with their possessions. The Charaideo Moidams in Assam were inscribed as a UNESCO World Heritage Site in 2024, becoming India's 43rd World Heritage Site and the first cultural property from the North-East. They were neither army fortresses, nor recreation centres, nor battle drill centres — only burial grounds of royals and nobles. Hence only statement 3 is correct.
