Assertion (A): Devaluation of a currency may promote export. Reason (R): Price of the country's products in the international market may fall due to devaluation.

1. Assertion (A): States that devaluation of a currency may promote export. Devaluation makes a country's goods cheaper for foreign buyers (when priced in foreign currency), thus potentially increasing demand and boosting exports. Assertion (A) is true. 2. Reason (R): States that the price of the country's products in the international market may fall due to devaluation. This is the mechanism through which devaluation works to promote exports – the foreign currency price decreases. Reason (R) is true. 3. Explanation: The fall in the international market price (Reason R) is the direct cause for the potential promotion of exports (Assertion A). Thus, R is the correct explanation for A. 4. Conclusion: Both A and R are true, and R is the correct explanation of A.
