Primary regions where subsistence agriculture is practiced include all of the following places except
a. africa
b. canada
c. central america
d. southeast asia

Correct answer. b. Canada

Explanation:

Subsistence agriculture refers to when farmers only farm for their subsistence, for their own consumption not growing more than they need and not selling most of their crops. This practice is often related as a survival method for poor countries where people have the necessity of growing their own crops to have food, in technical words Subsistence agriculture is for increasing their food security ( Availability of food).

This practice is most common in developing countries (countries in Africa, Central America, Southeast Asia, Latin America) where food availability is a problem yet to be solved, therefore in countries like Canada that have large supplies of food due to their agricultural practices such as industrial agriculture and mass production, they don't need to cultivate for their own consumption and all of their products can be destined for selling and not their survival.
