What increased through sea routes in India's world contacts?

Maritime trade

Sea routes made it easier for India to communicate and trade with distant regions. Ships could carry goods, people, ideas, and cultural practices across the seas. Thus, maritime routes strengthened India's links with other countries and helped Indian products reach foreign markets. The important idea is that geography and transport supported contact and exchange.

Option B is correct because maritime trade directly refers to buying and selling goods by sea. Products such as spices, textiles, and other valuable items could travel between India and different parts of the world. Polar isolation, the end of land boundaries, and glacier expansion have no logical connection with increased world contact through sea routes. Therefore, the supplied answer correctly identifies maritime trade.
