The correct answer is A (Initial Public Offering (IPO)) because private equity investment strategies, such as leveraged buyouts (e.g., MBOs and MBIs) and venture capital, typically employ primary exit strategies like trade sales, IPOs, and recapitalizations. An IPO is a common method for private equity funds to exit their investments by offering shares to the public. Options B (Management Buy-In) and C (Management Buyout) are incorrect as they represent investment strategies rather than exit strategies.
