Identify the diagram that best represents the relationship among the given classes.
Food Supplement, Bournvita, Horlicks

Let's evaluate the conceptual relationship among the three given groups:
Both Bournvita and Horlicks are distinct commercial brands of nutrition drinks, which are categorized fundamentally as Food Supplements.

Bournvita and Horlicks are entirely independent entities with no overlapping membership.

Therefore, the Venn diagram layout will feature two separate disjoint circles (representing Bournvita and Horlicks) contained completely inside a larger outer bounding circle (representing Food Supplements). This matches the visual structural representation in Option C.
