Why are "inert ingredients" included in pesticide formulations?

For enhanced pesticide efficacy
To reduce the volume of the pesticide
For immediate effect on pests
Because active ingredients are often not suitable for application

The correct answer is: Because active ingredients are often not suitable for application

Inert ingredients are included in pesticide formulations because the active ingredients alone may not be suitable for application. The inert ingredients are necessary to aid in the delivery and effectiveness of the active ingredients, rather than having an independent effect on pests. Additionally, they may also help with solubility, stability, and spreadability of the pesticide on the target area. This ultimately leads to enhanced pesticide efficacy, making option A incorrect. Option B is incorrect because the addition of inert ingredients does not necessarily reduce the volume of the pesticide. Option C is incorrect because the presence of inert ingredients does not immediately affect pests, as they do not have direct pest-killing properties.
