Answer :
Final answer:
The Double Bass is the lowest-sounding member of the string section in an orchestra due to its longer string length and larger size.
Therefore, the correct option is (a) Double Bass.
Explanation:
The instrument that produces the lowest-sounding notes in the string section of an orchestra is the Double Bass. This is due to the size and length of its strings which are significantly longer than those of the violin, viola, and cello.
When these strings are played, they vibrate at lower frequencies, producing lower-pitched sounds. Instruments such as violins and guitars use resonance in their sounding boxes to amplify and enrich the sound created by their vibrating strings, but the double bass has the lowest range among them.
