Which granulation method forms a wet mass by adding a binder and then dries after sieving?

• A. Dry Granulation
• B. Wet Granulation
• C. Fluid Bed Granulation
• D. NOTA

Answer: (B)

Wet granulation binds powders into a cohesive wet mass by adding a binder, then dries the material after it has formed granules through screening or granulation. The binder creates the moisture-needed cohesion to make the powder mix form lumps that break into uniform granules when sieved, and drying then removes that moisture so the granules are stable for further processing. The other methods don’t follow this exact sequence: dry granulation relies on compression without a liquid binder, and fluid bed granulation involves spraying binder into a fluidized bed to form granules (often with concurrent drying) rather than first forming a distinct wet mass in a mixer. NONE OF THE ABOVE doesn’t apply here.
