The Fat Lady is trying to produce a sound with high amplitude (loudness) and high frequency (pitch). This is evident from the fact that she is trying to break a glass with her singing voice, which requires a high intensity of sound waves. Furthermore, high-pitched sounds have a higher frequency compared to low-pitched sounds. Therefore, option B (high amplitude, high frequency) is the most suitable choice.
