What is the frequency range of a standard guitar?

The frequency range of a standard guitar primarily falls within the 82 Hz to 330 Hz range, making this the correct choice.

This range encompasses the fundamental frequencies of the open strings of a standard guitar, which starts from the low E string (approximately 82 Hz) up to the high E string (around 330 Hz). The human ear perceives these frequencies clearly, which is key for the acoustic qualities of the guitar, making it a versatile instrument in various musical styles.

The other options do not accurately capture the complete frequency range of a standard guitar, either falling below the low E string's frequency or extending beyond the typical range that encompasses the guitar's tonal capabilities. Therefore, acknowledging that the standard guitar's primary frequencies lie between 82 Hz to 330 Hz helps in understanding its role and sound production in music.
