Identify the diagram that best represents the relationship among the given classes:
Prime Minister, Chief Minister, Governor, State

Let's analyze the relationship between the entities:
A State contains both a Chief Minister and a Governor as part of its governance infrastructure. Thus, the circles for Chief Minister and Governor must be entirely inside the larger circle representing State.

The Chief Minister and Governor hold separate, distinct posts, so their circles do not overlap.

The Prime Minister belongs to the central/federal executive government of the country, which is a completely separate entity from any individual state's executive domain. Hence, the circle for Prime Minister stays outside independent of the State circle.

This classification arrangement matches a configuration where two disjoint circles lie inside a large circle, and a third distinct separate circle is completely outside.
