The question asks about why you can distinguish your mother’s voice from your sister’s on the telephone despite identical pitch and loudness, pointing to a perceptual quality. 
Option frequency: This refers to how often the waveform repeats per second and is tied to pitch. Since the prompt states the voices have the same pitch, frequency cannot account for the ability to tell them apart, so this is not the correct choice.
Option wavelength: Wavelength is the spatial distance over which a wave’s shape repeats; in sound perception, it relates to frequency and the medium, but it is not the perceptual quality that differentiates voices beyond pitch. Given the same pitch, wavelength differences would not explain perceptual distinguishability in this context, so this is not the right answer.
Option timbre: Timbre is the perceptual attribute that allows us to discriminate different sounds that have the same pitch and loudness, such as two voices, instruments, or phonemes, due to spectral content, harmonicity, and other sonic characteristics. This is precisely the factor that enables you to tell your mother’s voice from your sister’s on the phone when their fundamental frequencies (pitch) and amplitudes (loudness) are matched.
Option amplitude: Amplitude corresponds to loudness. Since the question states equal loudness, amplitude cannot explain the difference in identity between the voices, so this option is incorrect.
Option tone timbre: This option seems to combine two terms; however, the commonly accepted term is simply timbre. The inclusion of “tone timbre” is either redundant or a distractor, and it does not present the standard perceptual quality by itself. Therefore, it is not the best answer compared to timbre alone.
In summary, the distinguishing factor at play here is timbre, the quality that differentiates sounds beyond pitch and loudness, which aligns with the scenario described. The other options either correspond to aspects that are specified as equal (pitch/frequency, loudness/amplitude) or introduce an awkward redundancy that does not add explanatory value.
