Identify the diagram that best represents the relationship among the given classes:
Sweets, Sugar, Salt, Jaggery

Let's analyze the logical intersections among the categories:
Both Sugar and Jaggery are separate sweetening substances, and both completely fall under the broader class of Sweets.

Salt is entirely distinct from sweets, sugar, and jaggery.

Therefore, the correct diagram consists of a large circle (Sweets) containing two non-overlapping smaller circles (Sugar and Jaggery), with a completely separate circle next to it for Salt. This matches the arrangement in option A.
