The correct option is A 200 years
Danish India was the name given to the colonies of Denmark in India, forming part of the Danish colonial empire. Denmark-Norway held colonial possessions in India for more than 200 years, including the town of Tharangambadi in present-day Tamil Nadu state and Serampore in present-day West Bengal. The Danish presence in India was of little significance to the major European powers as they presented neither a military nor a mercantile threat.
However, they never concentrated in India and sold their ports to the British and left India.
