Answer:
Nomad means Option C: People with no permanent home.
Step-by-step explanation:
Nomads are the people who do not have a home that is permanent. They wander from place to place for food and shelter. They also depend on climate and availability of plants and animals for their movement.
Aryans were the nomadic tribes who came from the north of the 'Caucasus Mountains'. These Aryan tribes migrated to India independently and gradually they settled in Indus Valley. Here they brought their culture, language and custom. As they began to settle, they stopped living as 'nomads'.
