Correct answer: A
Concept
In a Venn diagram, an intersection contains elements that belong to every named set. A condition such as “not in a set” removes the part lying inside that set.
Application
“Scientists who are politicians” means the intersection S ∩ P.
“Non-Indian” excludes circle I, so the required set is (S ∩ P) minus I.
In the diagram, the part common to S and P but outside I is labeled f.
Cross-check
Region d is shared by I and S but lies outside P.
Region a belongs to all three circles I, S and P.
Region c lies only in I.
Therefore, the required region is f.
