  1. A. Rhythm
  2. B. Resonance
  3. C. Acoustics (Correct answer)
  4. D. Announce

Correct Answer

Option C — Acoustics

Detailed Solution & Explanation

Acoustics is the branch of Physics (and engineering) concerned with the study of sound -- its production, transmission, reception, properties, and effects. The word comes from the Greek "akoustikos" meaning "relating to hearing." Acoustics covers topics such as wave properties of sound, echo, resonance, the Doppler effect, ultrasound, and the design of concert halls for optimal sound quality. Rhythm is a pattern in music/poetry; resonance is a specific phenomenon within acoustics; Announce is a verb, not a branch of science.
