Correct Answer: drying agent

Solution : The correct option is a drying agent.

Silica gel is a typical drying agent used to absorb moisture and humidity. Small packets of silica gel are frequently found within product packaging to assist in preventing moisture damage, such as in electronics, clothes, and food products. It works by adsorbing (rather than absorbing) moisture, which means it attracts and retains water molecules on its surface. It should be noted that silica gel is not intended for human consumption and should be kept away from food.
