Explanation

Exhaust mufflers (B), isolation techniques (C), and mounting techniques (D) are the three correct answers because they each directly address how sound is generated or transmitted to surrounding areas: mufflers suppress exhaust noise at the source, isolation techniques (such as acoustic enclosures or barriers) block sound from propagating outward, and mounting techniques (such as vibration pads or anti-vibration mounts) reduce structure-borne noise caused by engine vibration. Fuel quality (A) affects combustion efficiency and emissions but does not meaningfully reduce noise levels. Prime mover cooling techniques (E) relate to thermal management of the engine and have no direct impact on sound output. A helpful memory device: think "MIM" - Muffler, Isolation, Mounting - the three physical interventions that intercept noise at the source, the path, and the structure.
