Answer:
The correct option is A,those products had been cheaper to import than they were to make within country Z's fledgling industries.
Step-by-step explanation:
Protecting infant industries is one strategy the government might favor in order to ensure reduction in the level of unemployment in the economy.
Judging from the scenario, the fact that the cost of the products to the buyers increased implies that the locally-made one is more expensive than the imported one,hence the fledgling ,immature industries could not compete favorably with their foreign counterparts in terms of pricing,which necessitated government to wade in to save the fledgling industries from going under.
Besides,the cost of the product of export-dependent industries in Z ,increased due to increase in price of their input which they have to source from the fledgling industries,thereby making them less competitive in the export markets.
