Which is the wrong cause-effect relation in India-world relations?

Correct answer: Contact routes made India completely isolated

Direct answer: Option D is the wrong cause-effect relation. India’s favourable location between regions and near important sea routes helped people make contact, so Option A is correct. Once routes existed, travellers, merchants, religions, languages, ideas, and goods could move, so Option B is correct. Sea routes made long-distance exchange and commerce easier, so Option C is correct. Option D reverses the actual result: contact routes did not make India completely isolated; they connected India with other societies and encouraged exchange. Therefore D is the wrong relation. Option A is not selected because favourable location can increase contact. Option B is not selected because routes carry both material goods and ideas. Option C is not selected because maritime trade is a major form of commerce. The important reasoning chain is location and routes → contact → movement of goods and ideas → exchange. Common mistake: do not confuse “outside influence” or cultural change with complete isolation.
