Rationale: The Real Estate Commission's authority does not extend to regulating commission rates, as these are typically determined by market forces and individual agreements between parties.
Option A is incorrect because the Commission does have the power to suspend or revoke real estate licenses to ensure compliance with regulations.
Option B is also incorrect; the Commission can subpoena witnesses to gather necessary information during investigations.
Option D is wrong as well; the Commission has the authority to review brokers' escrow or trustee accounts to ensure proper handling of client funds.
