Referring to question Q.164 in image_b9bd15.png, which of the following logical diagrams correctly represents the relationship between Musicians, Instrumentalists, and Violinists?

Let's look at the categorical hierarchy between the three groups:
1. Every Violinist plays a violin, which is a musical instrument. Therefore, all violinists belong to the group of Instrumentalists ($\text{Violinists}\subset \text{Instrumentalists}$).
2. Every Instrumentalist creates or plays music, meaning all instrumentalists belong to the broader group of Musicians ($\text{Instrumentalists}\subset \text{Musicians}$).

Since one class is completely contained within the next, this structural containment is logically depicted by three nested concentric circles, which matches Figure A.
