Final answer:
A concentric diversification strategy involves a company adding new, related business ventures to leverage its existing core competencies, potentially reducing costs and increasing efficiency.
Step-by-step explanation:
A concentric diversification strategy is a business approach where a company adds new products or services that are related to its existing product lines and can benefit from the company's current strengths and capabilities. This strategy is often utilized to achieve competitive advantage by leveraging the firm's core competencies in related markets. Option C is correct, as a concentric diversification strategy is used to add new businesses that produce related products or are involved in related markets and activities.
