问题如下：
A large country can:
选项：
A. benefit by imposing a tariff.
B. benefit with an export subsidy.
C. not benefit from any trade restriction.
解释：
A is correct.
By definition, a large country is big enough to affect the world price of its imports and exports. A large country can benefit by imposing a tariff if its terms of trade improve by enough to outweigh the welfare loss arising from inefficient allocation of resources.
考点：Trade Restrictions
解析：大国可以影响世界价格。因为大国需求大，关税降低了需求，从而迫使价格下降。消费者福利损失因此减少，所以A正确，C选项错误。
对于export subsidy，这类补贴政府掏钱，那么出口越多，政府收入损失越大。
