Critical Reasoning

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia. Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed. However, recent statistics show a drop in the number of television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.

Which of the following is an assumption on which the argument depends?

A. The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.

B. Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.

C. The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.

D. The number of televisions assembled annually in Vernland has increased significantly during the past three years.

E. The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years

Answer is C

Certainly answer is C because that breaks the argument. But what is wrong with D ?
How can i eliminate D ?

The explanation says,"The argument does not depend upon this being so: Vernland's domestic TV sales may have decreased by more than its imports into Borodia have increased.

I assumed that the drop in the number of television assemblers in Borodia has led to lower production of T.V's and this has increased the imports from Vernland. But with this import the production of TV in Vernland has also increased.
