The correct answer is A) command economies and market economies.
The two most common types of economic systems in South and Southeast Asia are command economies and market economies.
Let's first define a command economy. This kind of economic system exists in countries where the government determines the goods that should be produced, as well as the quantity and the price of the goods. In market economies, is the free market that establishes the supply and the demand.
The economies of South and Southeastern countries are part of command economies and part market economies. For instance, North Korea and Myanmar are command economies. The presence of the State in economic activities is total and it regulates the supply and demand of products. India and Philipines are market economies, where the free market dictates the products to be sold and the price.
