Which thing that went out from India is most correctly a trade item?

Correct answer: Spices

Direct answer: Option B, spices. A trade item is a physical good that people buy, sell, carry, or exchange. Indian spices such as pepper and other aromatic products were valued in long-distance trade and travelled to outside regions. Option A, the Upanishads, is a group of philosophical and religious texts. They could spread as knowledge, but they are not normally classified as a material trade commodity in this question. Option B is correct because spices are clearly physical goods traded from India. Option C, the decimal system, is mathematical knowledge, not a physical product. It travelled through teaching and intellectual exchange, but that is different from being a trade item. Option D, Greek sculpture, originated in the Greek cultural world and is not something that went out from India. The important distinction is between goods and ideas: goods are traded materially, while knowledge and cultural traditions spread through learning and contact. Memory cue: when asked for a trade item, choose a product that can be packed, carried, and sold.
