O.C.G.A. § 33-9-4 lists three statutory rate standards Georgia rates must satisfy. Which set correctly states them?

Why this is the answer

O.C.G.A. § 33-9-4 sets the foundational test for every Georgia P&C rate: it must not be excessive (overcharging consumers), inadequate (threatening insurer solvency), or unfairly discriminatory (charging different prices to risks of substantially similar exposure without an actuarial basis). These three prongs guide every Commissioner approval decision and underlie disapproval orders, market-conduct exams, and consumer complaints. The standards apply to every rate, whichever filing procedure § 33-9-21 prescribes for the line.
