Which defining feature is associated with soprano singers?

The defining feature associated with soprano singers is their ability to possess a vocal range that typically exceeds an octave. Soprano voices are known for their high pitch and are often the highest in choral arrangements and operatic performances. The standard soprano range is generally recognized to extend from about middle C (C4) to high C (C6) or even higher, depending on the singer's abilities. This extensive range allows soprano singers to perform melodies that are bright and prominent within a musical composition.

Other choices do not accurately represent the characteristics of sopranos. While bass singers have a much lower vocal range, it is not accurate to say that sopranos can sing lower notes than them. Soprano singers do interact with tenors, but their roles in harmony do not define them. Lastly, sopranos can be both male (countertenors) and female; thus, the statement about comprising only male singers is misleading.
