The appreciation of the Indian rupee against the Chinese yuan implies that the value of the Indian currency has increased relative to the Chinese currency. This means that for the same amount of yuan, a Chinese importer can now buy fewer Indian rupees. Consequently, the cost of Indian goods, which are priced in rupees, will effectively increase for Chinese importers. This is because they now need more yuan to buy the same amount of rupees, and hence the same quantity of goods. On the other hand, for Indian buyers, Chinese goods will become cheaper. This is because the Indian rupee, having appreciated, now has more purchasing power. Therefore, for the same amount of rupees, an Indian buyer can now buy more yuan, and hence more Chinese goods. This dynamic is a fundamental principle of international trade and foreign exchange.

Choice A is incorrect. This choice suggests that Indian goods will be cheaper for Chinese importers, while Chinese goods will become more expensive to Indian buyers. However, this is not the correct outcome of rupee appreciation - the opposite is true.
