Which of the following diagrams indicates the best relation between Hospital,…

Concept: In a three-term Venn diagram question, the diagram shape must match the real relationship between the three terms. A subset relation (one term entirely contained in another) is shown by concentric circles; a partial overlap between all three terms is shown by three mutually intersecting circles; and two distinct-but-related categories that both belong to one larger group are shown as two separate, non-overlapping circles placed inside one larger circle for that group.

Application: Here, Hospital is the overall organisation, while Nurse and Patient are two distinct categories of people found within it. A nurse is not a patient and a patient is not a nurse, so the two categories do not overlap with each other, yet both nurses and patients belong to the hospital. This is exactly captured by one large circle for Hospital containing two separate, non-touching circles for Nurse and Patient.

Cross-check, why the other layouts do not fit:

• Three circles that all overlap each other in pairs and in the centre would mean the three categories partially share members with one another, but Hospital is the containing organisation, not a category that partially overlaps with Nurse and Patient.

• Three circles nested one entirely inside the other (concentric) would mean each category is a subset of the next, for example, every patient is also a nurse, which is not the case, since nurses and patients are separate groups.

• Two circles nested inside each other plus a third circle sitting completely apart would mean a subset relation between two categories while treating the third as unrelated, this also fails to show both nurses and patients as distinct groups belonging to the hospital.

So the diagram of one large circle for Hospital containing two separate, non-overlapping circles for Nurse and Patient best represents the relationship.
