Final answer:
A personal checking account of a real estate licensee does not qualify as a trust fund by definition as it's used for personal finances and not to hold client funds.
Step-by-step explanation:
Among the choices provided, C. A personal checking account of a real estate licensee is NOT an example of a trust fund as defined in the Minnesota statute. Trust funds in real estate are special accounts where money is held on behalf of the clients and are separated from the licensee's personal funds or business operating accounts. An earnest money account, a security deposit held by a property manager, and an escrow account for property tax payments all serve the purpose of holding funds for the benefit of a party or for a specific purpose related to real estate transactions. However, a personal checking account of a real estate licensee does not protect clients' funds and is not for the purpose of holding funds in trust for others as required by the statute.
