Final Answer :
B
Explanation :
First-generation pesticides are those that were developed and used prior to World War II. Rotenone was one of the earliest pesticides used and is therefore considered a first-generation pesticide. Catechin is a type of flavonoid found in plants and is not a pesticide. DDT and chlorinated hydrocarbons were developed and used after World War II and are not considered first-generation pesticides.
