Final answer:
The heartland cities for the province of British Columbia, acting as its central economic and cultural hubs, are both Vancouver and Victoria, hence the correct answer is c. A and B.
Step-by-step explanation:
In the context of the hinterland-heartland framework, British Columbia can be considered as its own hinterland due to its economic activities that are complementary to a central region. The heartland, which is generally the more populous and economically developed area that serves as a focal point of economic activity, would be the major cities within British Columbia. Given the options provided in the question, the correct answer would be c. A and B, which implies both Vancouver and Victoria act as the heartland for British Columbia. Vancouver is a key economic center with a large population and diverse industries, while Victoria is the capital city and also plays a significant role in the political and cultural aspects of the province.
