Answer:
B
Step-by-step explanation:
Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year
GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export
Net export = exports – imports
Investment spending includes inventory purchase by businesses. When an Egyptian firm purchases a cement mixer, the Egyptian's investment increases.
Also, because the mixer is bought from Slovakia, it is regarded as an import. Because import is a negative function of net export, net export decreases#
The increase of investment and the decrease in net export, cancel out each other. As a result, GDP does not change.
Slovakian net export increases because export is a positive function of net export
