The correct answer is (a) 2016.
Ramman is a traditional folk dance of the Kumaon region of Uttarakhand. It is performed during the month of Chaitra (March-April) to celebrate the arrival of spring. The dance is performed by a group of men and women who wear colorful costumes and masks. The dancers move in a circular formation and perform intricate steps to the accompaniment of music played on drums and other instruments.
In 2016, Ramman was a part of the Uttarakhand tableau at the Republic Day parade in New Delhi. The tableau depicted the dance and its significance in the culture of Uttarakhand. The tableau was well-received by the audience and was praised for its depiction of the rich culture of the state.
The other options are incorrect because they are not the years in which Ramman was a part of the Uttarakhand tableau at the Republic Day parade in New Delhi.
