Explanation: Laissez-faire (“leave it alone”) is the principle that governments should not interfere in or regulate industries, businesses, or markets. Totalitarian governments typically have total control over their economies, making “A” the better answer (B). Utilitarian philosophers advocate policies that create the greatest amount of happiness for the largest number of people. It is not a style of government per se, nor would it be consistent with systems that used child labor (C). Corporatists include interest groups (like labor and industry) in the government, and therefore provide more government involvement in the economy than laissez-faire systems (D).
