What type of products do aerosols (A) primarily consist of?

Aerosol products primarily consist of a low percentage of active ingredients in a solvent, which is the correct choice. This formulation allows for the even dispersal of the active component through a fine mist or spray when the aerosol is used. The solvent helps to dissolve or suspend the active ingredients, enabling their effective application over a surface or area.

Aerosols are designed to provide a convenient method for using pesticides or other chemical products, and the low concentration of active ingredients ensures that they can be safely and effectively applied in various settings without overwhelming the area with fumes or residues. The balance between the solvent and the active ingredient is crucial for ensuring that the product delivers the intended efficacy while maintaining ease of use.

Understanding the composition of aerosol products is important for proper usage and compliance with safety standards in vector control practices.
