Step 1: Understand the Venn diagram.
Circle A: Indians
Circle B: Teachers
Circle C: Musicians
We need to find the region that lies in both A (Indian) and B (Teacher) but not in C (Musician).
Step 2: Identify intersection.
The region satisfying this condition is the part where Indian and Teacher overlap but does not touch the Musician circle.
In the diagram, this corresponds to region (B)
Step 3: Confirm exclusion from Musician circle.
The region b lies only in the intersection of Indian and Teacher.
It is clearly outside the Musician circle.
