参考答案:  C


本题详细解析:

C

$\underset{‾}{\text{Explanation}}$:
When a tariff is imposed:

• The domestic quantity supplied is at the intersection of the $S_{domestic}$ and the $S_{world+tariff}$ curves (125 000 units).
• The domestic quantity demanded is at the intersection of the $D_{domestic}$ and the $S_{world+tariff}$ curves (275 000 units).
• The quantity of imports is the difference between domestic quantity demanded and supplied (275 000 $-$ 125 000 = 150 000 units).

Choices A, B, and D are incorrect because they confuse pre-tariff figures with post-tariff figures for at least one of the variables.
