What type of pesticide is specifically formulated to control snails and slugs?

The correct choice is indeed the one that identifies molluscicides as pesticides specifically formulated to control snails and slugs. Molluscicides are designed to target the unique physiological characteristics of mollusks, which include snails and slugs. These pests can cause significant damage to gardens and crops, and thus a specialized type of pesticide is necessary to effectively manage them without impacting other types of organisms.

In contrast, herbicides are formulated to control unwanted plants and weeds, insecticides focus on insect pests, and fungicides are aimed at controlling fungal diseases. Each of these categories plays a distinct role in pest management, but only molluscicides are tailored to address the specific challenges posed by mollusks. This specialized formulation is crucial because using the wrong type of pesticide could result in ineffective control and potentially harmful environmental consequences.
