Which of the following is a common name for a pesticide?

Fipronil is recognized as a common name for a pesticide because it is a widely used active ingredient classified under the phenylpyrazole group of pesticide compounds. Fipronil is notable for its effectiveness in controlling a variety of pests, including insects and fleas, making it a popular choice among pest management professionals and in agricultural applications.

The other options present chemical names or concepts that do not qualify as common pesticide names. For example, the name provided in option C is an IUPAC (International Union of Pure and Applied Chemistry) name, which, while precise, is not commonly used in everyday practice or conversation regarding pesticides.

Similarly, Wisdom TC in option A is a brand name for a specific pesticide formulation that contains the active ingredient, but it is not the common name of a universally recognized pesticide. Meanwhile, heat treatment in option D refers to a method of pest control rather than a pesticide itself. This further establishes Fipronil as the clear answer, reflecting its status as a well-known and utilized pesticide in various sectors.
