Which of the following is an example of a brand name for a pesticide?

The example of a brand name for a pesticide is Roundup. Brand names are specific labels assigned to products by manufacturers to distinguish their formulations from others available on the market. Roundup is a well-known brand that contains glyphosate as its active ingredient, specifically formulated for weed control. This brand recognition helps consumers identify and choose a product based on reputation, efficacy, and marketing.

In contrast, glyphosate refers to the active chemical ingredient used in many herbicides, but it is not a brand name. Herbicide 123 might suggest a specific formulation but does not specify a recognized brand as it sounds more like a generic or placeholder name rather than a marketed product. Pest Control Agent is vague and could refer to many products or methods used for pest management but lacks the specificity that a brand name provides. Thus, Roundup is indeed the correct choice as it represents a unique product line within the broader category of herbicides.
