Botanical pesticides are made from what?

Botanical pesticides are derived from plants or plant parts, which is what makes option B the correct answer. These pesticides utilize the natural compounds found in various plants that have insecticidal or repellent properties. Many botanical pesticides, such as those made from neem, pyrethrum, or diatomaceous earth, are used in organic gardening and agriculture because they are often considered less harmful to beneficial insects and the environment compared to synthetic chemicals.

The extraction of these natural substances from plants means that they often break down more quickly in the environment and tend to be safer for humans and wildlife when used appropriately. This focus on plant-derived ingredients aligns with sustainable practices that aim to minimize chemical exposure in ecosystems.

In contrast, minerals, synthetic chemicals, and animal by-products do not fit the definition of botanical pesticides as they do not derive from the botanical source, thus highlighting why option B accurately identifies the composition of botanical pesticides.
