Why are spices and muslin considered important in India's old contacts?

Correct answer: They were linked with India's old trade and external demand

The direct answer is A: spices and muslin were connected with India’s old trade and demand from outside regions. Spices are valuable flavouring goods, while muslin is a fine cotton cloth. Merchants carried such products through land and sea routes, and foreign buyers wanted them. Therefore, they show economic contact between India and other places. Option A is correct because it identifies them as traded goods. Option B is wrong because spices and muslin are products, not routes; roads and sea lanes carried them. Option C is wrong because they are not architectural styles such as designs of buildings. Option D is wrong because “polar ideas” has no meaningful connection with historical Indian trade. Memory cue: goods travel on routes; goods themselves are not routes.
