Correct option is C
Correct Option: c)
Information Booster:
· Assertion A is true: The three primary psychoacoustic qualities of a musical sound are indeed Pitch (perception of frequency), Intensity/Loudness (perception of amplitude), and Timbre (tonal colour/texture, determined by harmonics).
· Reason R is false: It states, "Musical sound does not have any relation to frequency."
· This is fundamentally incorrect. Pitch, which is a defining quality of musical sound, is directly and intrinsically related to the fundamental frequency of the sound wave.
· Frequency is its physical cause.
Additional Knowledge:
· Since A is true and R is false, the correct choice is that A is true but R is false.
