Answer 2

Answer: Option (D) is the correct answer.

Step-by-step explanation:

A pure substance is defined as a substance that does not contain any kind of impurity and it can be a compound or an element whose composition does not vary.

For example,
`Cl_(2)`,
`CaCl_(2)` etc are all pure substances.

Pure substances have a fixed melting and boiling point.

A compound is defined as a substance that contains different type of atoms that are chemically combined together in a fixed ratio by mass.

An impure substance is defined as a substance that contains some kind of impurity and whose composition also varies.

A mixture is defined as a substance in which two or more substances are present but they are not chemically combined to each other. A mixture can be homogeneous or heterogeneous in nature.

Thus, we can conclude that Bromine can be classified as a pure substance.
