    a.) high amplitude, high frequency

    Explanation:

    Frequency and amplitude are properties of sound. Varying these properties changes how people perceive sound.

    While hearing sound of a particular frequency we call it pitch i. e., the perception of a frequency of sound.

    High pitch means high frequency and high frequency is perceived to have a shrill sound.

    The loudness of a sound is measured by the intensity of sound i. e., the energy the sound possesses per unit area. As the amplitude increases the intensity increases. So, a loud sound will have higher density.

    Hence, the loud shrill whistle will have high frequency and high amplitude.
