Final answer:
The potential demand for a product within a country is influenced by a combination of macroeconomic factors including economic growth, unemployment rate, inflation, and disposable income; thus, 'All of the above' is the correct answer.
Step-by-step explanation:
The potential demand for a product within a country depends on various macroeconomic factors including Economic growth rate, Unemployment rate, Inflation rate, and Disposable income. Therefore, the correct answer is E. All of the above. Factors such as a rise in the natural rate of unemployment, rising inflation, and a rise in oil prices can have a significant impact on the demand for a product. Additionally, changes in the economic conditions of other countries, especially those that are major importers, can also affect a nation's exports. For instance, if countries that import American-made products experience recessions, this would likely result in a decrease in demand for those exports.
