Answer:
A. Characterized by the quality of being not divisible into parts.
Explanation:
The word 'Individuality' exemplifies the distinguished yet distinctive characteristics of a particular person. It displays the quality of being individual in contrast to the community or class. As each singer has a distinct feature of them that they do not share with other people and which makes them unique, for which they are known. Thus, Individuality illustrates "the quality of being a particular character" and not the "generalized or divisible into parts". It refers to the quality of being "in-divisible" and the one who has a "separate existence" distinguished from the others.
