Step 1: Understanding the Question:
Exchange rate here means the amount of domestic currency (Rupees) needed to buy one unit of foreign currency. A rise in this rate means the Rupee has depreciated (weakened).
Step 2: Why option A is correct:
When the Rupee depreciates, foreign buyers need less of their own currency to buy the same amount of Rupees, so Indian goods become cheaper for foreigners — India's exports become cheaper (more competitive) in foreign markets.
Step 3: Why option B is wrong:
Depreciation makes imports costlier, not cheaper, because Indian buyers now need more Rupees to purchase the same amount of foreign goods.
Step 4: Why option C is wrong:
This is the direct opposite of the actual effect: depreciation cheapens exports, it does not make them costlier.
Step 5: Why option D is wrong:
Imports are directly affected (they become costlier), so "no effect" is incorrect.
Final Answer:
A rise in the exchange rate (Rupee depreciation) makes exports become cheaper.
