Suppose That a Country's Factors of Production Are "Completely Specific

Suppose that a country's factors of production are "completely specific" to the industries In which they are located (i.e., factors in the X industry would contribute nothing to Y Output if they were employed in the Y industry and factors in the Y industry would Contribute nothing to X output if they were employed in the X industry) . In addition, Suppose that the country has an autarky P_X/P_Y that is greater than the world P_X/P_Y. In this
Situation, if the country is opened to international trade, it will

A) export good X and will obtain "gains from specialization" (a "production gain") but not "gains from exchange" (a "consumption gain") .
B) export good X and will obtain "gains from exchange" (a "consumption gain") but not "gains from specialization" (a "production gain") .
C) export good Y and will obtain "gains from specialization" (a "production gain") but not "gains from exchange" (a "consumption gain") .
D) export good Y and will obtain "gains from exchange" (a "consumption gain") but not "gains from specialization" (a "production gain") .
