The correct answer is C) They brought Sanskrit with them. The Aryans or better known as the Indo-Iranians are said to have brought Sanskrit to the region around 1500 BC in the Rigveda. This helped the Indo-Aryan language to spread until 500 BC to vast parts of the continent, all in different pivotal areas. The Indo-Aryans were then able to set up kingdoms and control the land. The descendant languages of the Indo-Aryan language are spoken in the Indian sub-continent today as well as in Fiji and the Maldives.
