Which one of the following four statements describes the advantage of using delta-gamma method of...

The delta-gamma method improves upon the delta-normal method by incorporating the gamma of the options, which accounts for the curvature in the price relationship of the option to the underlying asset. This method better captures the non-linear aspects of option pricing, especially for extreme price movements. Gamma measures the rate of change of delta with respect to the price of the underlying asset, thus allowing for a more accurate reflection of the option's risk profile. By including gamma, the delta-gamma method can more accurately represent the risks associated with both small and large movements in the underlying asset's price, making it particularly effective for capturing the full spectrum of option price risk.
