Refer to the Graph Above, Where S_d and D_d Are

Refer to the graph above, where S_d and D_d are the domestic supply and demand curves for a product. The world price of the product is $6. If the economy is open to international trade but a per unit tariff of $4 is imposed, then the total revenue going to domestic producers would be:

A) $400, the total revenue (after tariff) going to foreign producers would be $120, and the tariff revenue going to the government would be $80
B) $240, the total revenue (after tariff) going to foreign producers would be $240, and the tariff revenue going to the government would be $80
C) $400, the total revenue (after tariff) going to foreign producers would be $240, and the tariff revenue going to the government would be $80
D) $240, the total revenue (after tariff) going to foreign producers would be $120, and the tariff revenue going to the government would be $120
