What is an emulsion in pesticide formulations?

When water is dispersed in oil.
A solid active ingredient dissolved in water.
When one liquid is dispersed within another like oil and water.
A gas suspended in a liquid.

The correct answer is: When one liquid is dispersed within another like oil and water.

An emulsion in pesticide formulations refers to a mixture of two immiscible (unmixable) liquids, where one liquid is dispersed in the other in small droplets. This is different from a solution (option B) where one substance is dissolved in another. The other options, such as option A (water dispersed in oil) and option D (gas suspended in liquid) do not accurately describe an emulsion. It is important to understand the correct definition of an emulsion in order to properly formulate pesticides for effective use.
