Blotting paper absorbs ink due to A) Capillary action phenomenonB) Diffusion of ink through the blottingC) Siphon actionD) Viscosity of ink
The correct answer is Capillary action phenomenon. The absorption of ink by the blotting paper is based on the capillary action phenomenon because the blotting paper is a thin and smooth paper that allows a little thicker liquid like ink to absorb on its surface.
