Answer:
(D) The average productivity of the workers in the country has not risen.
Explanation:
The passage suggests the cause of workers' wages remaining low in companies which have increased their productivity is because it is influenced by average productivity in the country's economy. This is suggested within parentheses.
The author does not explain it any further that how it is influenced by country's average productivity. The reader can infer that it is because, when other companies in the country have not increased their productivity the competition for hiring better skilled workers remains easy, as a result even the high producing companies don't need to increase the wages significantly.
Options A, B and C are irrelevant to workers' low wages (in companies with increased productivity).
Option E is one of the factors, but the main factor has already been suggested by the author within parentheses right after the sentence (about low wages in companies with increased productivity).
