Final answer:
The pronghorn antelope is native to the Prairie Grasslands of Alberta, which is the ideal habitat for them, as opposed to the Rocky Mountains, Boreal Forest, or Foothills.
Step-by-step explanation:
In Alberta, you would find the pronghorn antelope in the C) Prairie Grasslands. Pronghorns are native to the interior of the western and central North America, where the vast Prairie Grasslands are found, providing the open spaces that pronghorns prefer for their habitat. They are not typically found in the Rocky Mountains, Boreal Forest, or Foothills environments, as these areas do not provide the extensive grassy plains that are characteristic of the pronghorn's natural habitat.
