Question

Which of the following diagrams indicates the best relationship between Teacher, Writer and Musician? 

 

• A. (a)
• B. (b)
• C. (c)
• D. (d)

Hint:

Use three intersecting circles when categories can overlap in any combination, including all three.

Answer 1

The Correct Option is B

The groups Teacher, Writer, and Musician are independent professions: a person may belong to any one, any pair, or all three (e.g., a teacher who is also a writer and musician). This requires three sets with pairwise and triple overlaps. 

Hence the best representation is three intersecting circles. \[ \boxed{\text{Option (b)}} \]

Answer 2

Let's classify the relationship type first, then match it to the standard diagram convention, rather than jumping straight to naming the diagram.

1. If the three groups were completely unrelated (no person could belong to more than one), the correct picture would be three separate, non-touching circles. But a person can easily be a teacher who also writes and plays music, so this "no overlap" picture doesn't fit here.
2. If one group were entirely contained in another (say, every musician were automatically a teacher), the picture would show one circle fully inside another. There's no such total-containment relationship stated or implied between Teacher, Writer and Musician, so a nested-circles diagram doesn't fit.
3. If only two of the three groups could overlap (say Teacher and Writer overlap, but Musician stands entirely apart), the picture would show two intersecting circles plus one separate circle. Since a person could just as easily combine any two of the three professions, or all three at once, restricting the overlap to only one pair understates the real relationship.
4. Since any individual may hold one, two, or all three roles simultaneously, each pair must overlap and all three must share a common region — this is exactly the picture of three mutually intersecting circles, which is option (b).

Matching the "any combination is possible" relationship to its standard diagram gives three overlapping circles.

Hence, the correct answer is (b).
