A pesticide is defined as a substance specifically designed to prevent, destroy, or control pests, including insects, weeds, fungi, and other organisms that can cause harm to crops, plants, or human health. This definition encompasses a wide range of chemical formulations that target unwanted organisms, making option A the most accurate description of what a pesticide is.

The other options presented do not adequately capture the essence of a pesticide. While landscaping products may include pesticides, they are not exclusively classified as such since many other products are used purely for aesthetic purposes without pest control functions. Similarly, health supplements for plants, which may improve plant health or yield, are not pesticides because they do not have the primary purpose of managing pests. Lastly, household cleaning agents focus on sanitizing or cleaning surfaces and do not function as pest control products. Thus, identifying a pesticide primarily as a substance for controlling or managing pests is vital for understanding its application and regulation.
