Which of the following is a correct statement about business cycles? a

The correct answer is a.

The average recession is shorter than the average expansion in a business cycle.

A recession is a stage in the business cycle in which economic and business activities decline, including production levels, sales levels, employment levels, and income levels. An expansion refers to the economic or business phase in which there is an economic increase in employment, sales, income, and production. These phases are marked by points like trough (marks the end of a recession) and peak (marks the end of an expansion). In the United States, economic expansions last longer than economic recessions because the country develops strategies that can help prevent economic and growth decline and protect the country from economic downturn phenomena like inflationary issues.
