Which of the following is NOT a method of valuation?

C is the correct choice because Discounted Value is not typically recognized as a standard method of property valuation in insurance. The other options represent established and widely accepted methods used to determine the value of insured property.

Actual Cash Value is calculated by taking the replacement cost and subtracting depreciation, reflecting the current worth of an item at the time of loss. Replacement Cost values the item based on the cost to replace it with the same or similar item without accounting for depreciation. Agreed Value is a method where the insurer and the insured agree on a specific value for the property at the inception of the policy, thus eliminating disputes in the event of a claim.

In the context of insurance, Discounted Value is more often associated with financial calculations, such as future cash flows or annuities, rather than valuing property for claims purposes. Therefore, it's correct to identify Discounted Value as not being one of the primary methods of valuation in an insurance setting.
