Final answer:
Life in the backcountry is most accurately portrayed by limited infrastructure, where access and utilisation of resources were often challenging due to sparse populations and rudimentary development.
Step-by-step explanation:
The statement most accurately portraying life in the backcountry is C. Limited infrastructure. In many historical contexts, backcountry areas were typically characterized by their sparse populations and rudimentary development. These areas did not have dense urban populations or high technological advancement, and while they may have had an abundance of natural resources, the lack of infrastructure made it challenging for settlers or inhabitants to access and utilize these resources efficiently. Life in the backcountry often involved rural communities with significant distances between them, a lack of well-constructed roads or transportation networks, and sometimes inadequate access to food and other necessities.
