Explanation:

This question tests knowledge of different types of private equity investments.

Key Concepts:

1. Growth Capital Investing: This involves making minority equity investments in mature companies that are seeking capital to expand or restructure operations, enter new markets, or finance a major acquisition without changing control of the business. The companies are typically profitable but need additional capital to fund growth initiatives.

2. Leveraged Buyout (LBO) Investing: This involves acquiring a controlling interest in a company using a significant amount of borrowed money (debt). The goal is often to improve operations and sell the company later at a profit. This is not a minority investment.

3. Development Capital Investing: This typically refers to investments in early-stage companies or projects that are still developing their business model or products. These companies are not yet mature.

Analysis:

• The question specifies a "minority equity investment" - this eliminates leveraged buyouts which are controlling investments.
• The company is described as "mature" - this eliminates development capital which targets earlier stage companies.
• The purpose is to "expand operations" - this aligns with growth capital investing where mature companies seek funding for expansion.

Therefore, the scenario described best matches growth capital investing.
