What becomes clear by studying spices, muslin and trade routes together?

Correct answer: India's goods trade was linked with the world

The direct answer is A: India’s goods trade was linked with the world. Spices were valuable products carried through land and sea routes, while fine muslin cloth was also made for buyers beyond India. The reasoning is: goods were produced; traders carried them along routes; distant regions received them; repeated exchange connected India with other societies. Option A is correct because it connects products with routes and international trade. Option B is false: the existence of spices, muslin and routes itself shows that trade occurred. Option C is false because these were not only polar goods; they were ordinary warm-region products traded across several regions. Option D is false because sea routes connected India to other parts of the world. The key lesson is that an object becomes evidence of wider contact when we study where it went and how it travelled.
