Answer: (B)

Verified step by step guidance

1. Understand the concept of pitch: Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale. It is primarily determined by the frequency of the sound wave.
2. Identify the typical frequency ranges: High-pitched sounds are usually associated with higher frequencies, while low-pitched sounds are associated with lower frequencies.
3. Analyze each sound option: Consider the typical frequency range of each sound. A screeching car tire, a screaming child, and a whistling tea kettle are generally associated with higher frequencies.
4. Consider the sound of a mooing cow: This sound is typically associated with lower frequencies compared to the other options, making it less likely to be interpreted as a high pitch.
5. Conclude based on frequency analysis: The sound with the lowest frequency range among the options is the mooing cow, which is least likely to be interpreted by the brain as a high pitch.
