What type of chemicals are specifically designed to eliminate mites and ticks?

The correct answer is C, as miticides are specifically formulated to target and eliminate mites and ticks. These chemicals disrupt the biological processes vital for mite and tick survival, effectively controlling their populations without harming other beneficial organisms. Miticides may work through various mechanisms, such as contact action or ingestion, and are critical in agricultural practices for protecting crops as well as in veterinary applications for managing parasite infestations in livestock and pets.

Insecticides are broader chemicals designed to manage insects, which include a wide range of species but do not specifically target mites and ticks. Herbicides are used to control unwanted plants or weeds and do not affect animals. Molluscicides are targeted at controlling mollusks, such as snails and slugs, and therefore do not apply to the elimination of mites and ticks. Understanding these distinctions helps ensure that appropriate pest control methods are employed in agricultural and horticultural practices.
