Silica gel packets, commonly found in packaging for shoes and electronics, serve what purpose?

AThey add a pleasant fragrance
BThey act as a fire retardant
CThey absorb moisture to help keep the contents dry
DThey prevent light from entering the package

Explanation

Silica gel is a porous, highly absorbent material that draws in and traps moisture from the surrounding air, which is why small packets of it are commonly included in packaging for shoes, electronics, and other items sensitive to humidity. By keeping the immediate environment inside the packaging dry, silica gel helps prevent mold growth, corrosion, or other moisture-related damage during storage and shipping. Despite sometimes carrying a warning label, silica gel itself is generally considered non-toxic, though the small packets pose a choking hazard for young children.
