Final answer:
The resource-based view of a firm aids in identifying a firm's 'core competencies', which are inherent strengths that provide a competitive advantage in the marketplace.
Step-by-step explanation:
The resource-based view of a firm is a strategic framework used to evaluate a company's internal capabilities. It aims to ascertain which resources and capabilities of a firm provide it with a competitive advantage or disadvantage in its marketplace.
Specifically, the resource-based view assists in identifying a firm's core competencies, which are unique strengths that allow it to outperform competitors. These competencies are what make a firm successful when it focuses on a limited range of products or services that it can produce exceptionally well, rather than diversifying into a wide range of products.
Thus, the resource-based view provides a model that systematically aids in identifying B) Core competencies.
This view contrasts with looking at a firm's external environment to explain competitive advantage. Within the resource-based framework, corporations leverage their unique competencies, like technology, skilled personnel, or efficient processes, to achieve and maintain a competitive edge in the market.
