Answer:
Option B represents a group of compounds as it consists of three different chemical compounds: copper sulfate (CuSO4), iron sulfate (FeSO4), and crystallized common salt (NaCl).
Explanation:
These three compounds have different chemical compositions and properties and are distinct from each other. Copper sulfate is a blue-colored salt used in various industries, iron sulfate is a greenish compound used in medicine and as a reducing agent, and crystallized common salt is a white compound used as a seasoning and preservative.
In contrast, options A, C, and D do not represent groups of compounds as they contain either element (such as air) or mixtures of compounds (such as seawater).
