Answer 1

The correct statement is A. If a substance is toxic, its toxicity is highly dependent on its form and where it is present in the environment.

Step-by-step explanation:

The correct statement is A. If a substance is toxic, its toxicity is highly dependent on its form and where it is present in the environment.

Substances can have different forms, such as solids, liquids, gases, and more. The form a substance is in can affect its toxicity and how it enters our bodies. For example, a toxic gas may be inhaled more easily than a solid form of the same substance.

Furthermore, the presence of a toxic substance in the environment can impact its toxicity. If a substance is concentrated or present in high levels in a certain area, it can pose a greater risk to organisms in that specific environment.
