• A. It is a safe pesticide with no health effects

• C. It is used as a fertilizer
• D. It is a natural plant extract

Answer: (B)

Chlordane is an organochlorine pesticide that was widely used to treat termites from the 1940s through the 1980s. It is toxic to humans and wildlife and does not break down quickly in the environment, so it persists in soil for years. This persistence means it can contaminate groundwater and can become airborne in dust or indoor air, posing exposure risks long after application. Because of these long-lasting effects, residues may need to be disclosed in real estate or health contexts due to potential exposure from legacy contamination. It isn’t a fertilizer and it isn’t a natural plant extract.
