Which statement is true regarding inorganic adulticides?

Inorganic adulticides are defined by their composition, which is the key reason why the statement about them containing no carbon atoms is accurate. Inorganic compounds typically include elements other than carbon and are usually composed of metals or nonmetals. While organic compounds consist of carbon-based molecules, inorganic adulticides are utilized in pest control for their effectiveness against adult insects.

This specific characteristic helps distinguish inorganic adulticides from organic ones, which are often more commonly used and contain carbon. The other statements do not accurately describe the nature or intended use of inorganic adulticides, making them less relevant in this context. For instance, inorganic adulticides do not exhibit a slow action; instead, they often have a rapid impact on target insect populations. Additionally, the primary use of these adulticides is not for larvicidal purposes; larvicides are specifically formulated to target larval stages of insects rather than adults.
