Borax, also called sodium tetraborate, is a powdery white mineral that has been used as a cleaning product for several decades. It has many uses: It helps get rid of stains, mold, and mildew around the house. It can kill insects such as ants.

Coffee stains are mostly tannins, pigments, and organic compounds, which respond best to mild alkaline cleaning agents that can break them down and lift them off fabric.Borax solution → mild cleaning agent, but not the most effective for tannin stains.Ammonia solution:
raises pH (alkaline medium)
helps dissolve and loosen tannin-based pigments in coffee
allows the stain to detach from fabric fibers more easily

The Correct answer is C; Coffee & tea stain on cotton and linens is removed by soaking in borax and water
