Hello!
Early Aryans were nomadic, they used to travel from place to place in order to find food. During meals they ate fruits, vegetables, fish and meat from their herds; this means that "herder" is a correct option, but once they settled in Nortwestern India, they learnt to farm the soil, so I would say that another correct option is the fourth one, "farmer"; they became farmers when they finally settled in India. Also, they were warlike people, they used to pass on war stories from one generation to another and also played fighting games, so the fifth one, "warrior", is the last correct option.
I hope this may help you
