Which of the following statement about complex modulus $(G^{**})$ of asphalt binder is Correct?

A$.$ The higher temperature, the higher G$*.$

B$.$ The higher loading frequency, the lower $G^{**}.$

C$.$ If $G^{**}$ is reduced by $5\%,$ the asphalt binder is most likely to be damaged.

D$.$ The storage modulus is calculated as the real part of the complex modulus, represented by $G^{**},$ multiplied by the cosine of the phase angle, where $$ is the phase angle.
