What type of contact was most increased by India's sea routes?

Correct answer: Maritime trade contact

Correct answer: B, maritime trade contact. Sea routes connect ports across seas, so they make the movement of ships, goods, merchants and ideas easier. India’s coastal position allowed it to communicate and trade with regions across the Arabian Sea, the Bay of Bengal and the Indian Ocean. This is why the question links sea routes mainly with trade and exchange. A is wrong because land-boundary contact uses roads and passes across neighbouring land areas, not sea routes. C is wrong because Indian sea routes were not mainly routes to polar regions. D is wrong because a mountain barrier is a physical obstacle, not a type of contact. Memory cue: sea route means ships, ports and maritime trade.
