The correct answer is A. According to the article titled “Prairie Provinces,” Canada’s prairie region contains four-fifths of the country’s farmland.
The Canadian prairies are a vast region of prairies that extends throughout the Canadian provinces of Alberta, Saskatchewan and Manitoba, which are considered prairie provinces. The region is characterized by having a sedimentary soil and by its slightly uneven relief. It is the most important Canadian agricultural area, despite only allowing a relatively short crop season, due to the long duration of the harsh winter.
