Which substance will absorb and inactivate pesticides when used to clean equipment and spills?

Activated charcoal is the correct choice as it is known for its exceptional ability to absorb and bind to a variety of substances, including pesticides. This property makes activated charcoal an effective agent in cleaning up pesticide spills and for decontaminating equipment. Its extensive surface area allows it to trap chemicals and toxins, therefore reducing the risk of harmful exposure and ensuring better safety when dealing with pesticides.

Baking soda, while potentially useful for cleaning in some contexts, does not possess the absorption qualities needed to effectively inactive pesticides. Bleach and hydrogen peroxide are both strong oxidizers and disinfectants but do not absorb chemicals or pesticides. Instead, they may react chemically with them, which could lead to the formation of harmful byproducts, rather than neutralizing the pesticides effectively.
