The correct answer is D. Structural adjustment programs, through their conditions, generally implement liberalization programs in a regulated and progressive way. These programs include internal and external changes, especially the reduction of trade barriers.
Some of the conditions for structural adjustment may include:
-A reduction in social spending, also known as austerity.
-Privatization of state-owned enterprises
-Balanced budgets and absence of excessive spending
-Trade liberalization or lifting of restrictions on the import and export
Therefore, a nation should not increase tariffs in order to receive a structural adjustment credit.
