Answer:
B, In response to low crop prices and overproduction, it is being replaced by intensive subsistence farming.
Explanation:
A market economic system is one in which laws of demand and supply determine the production of goods and services. Agriculture in market economic systems is not being replaced by subsistence farming because subsistence farming is low scale farming that meets the needs of a family and as such is not affected by any laws of demand and supply as in commercial farming.
