One of the fundamental principles of insurance rating is that thepremium charged must accurately reflect the level of riskbeing insured. This principle ensures fairness and financial stability: individuals or businesses presenting a higher probability of loss or greater potential severity must payhigher premiums, while lower- risk policyholders pay less. This is essential because insurers must collect sufficient funds to cover expected claims, expenses, and maintain solvency.
Option B describes the pooling of funds, which is part of how insurance works but does not address how premiums are determined.
Option C relates to the general purpose of insurance, not premium adequacy.
Option D loosely refers to indemnification, not rating methodology.
Therefore, the only statement that accurately reflects the idea that premiums must be commensurate with the risk isA.
