Which formulation is best described as no dust and premix not needed?

• A. Finely ground solid particles of AI suspended in a liquid carrier
• B. A clear liquid
• C. A dry powder
• D. No dust and premix not needed

Answer: (D)

The key idea is recognizing formulations by two practical traits: dust generation and whether premixing with water is required. A product described as having no dust and needing no premixing is a ready-to-use formulation that can be applied directly, without creating airborne dust and without diluting or mixing beforehand. Among the options, that exact description matches a ready-to-use product, making it the best choice. The other options describe forms that either involve loose dry solids (which can produce dust) or imply a preparation step (premixing) before use, so they don’t meet both criteria.
