By which organization are the rules and criteria used in scientific nomenclature accepted?

Correct answer: International scientific codes and committees

Correct answer: A, international scientific codes and committees. Scientific nomenclature needs common rules so that a biological organism has a stable and universally understood name. These rules are developed and accepted through international codes and expert scientific bodies. Different groups of organisms may be governed by separate nomenclatural codes, such as the botanical and zoological codes. The purpose is not that one country or school chooses the name, but that scientists across countries can communicate accurately. A is correct because international codes provide agreed standards for naming. B is incorrect because governments do not independently establish the universal rules of biological nomenclature. C is incorrect because a botanical garden may maintain and identify specimens, but it does not approve global naming rules. D is incorrect because school boards prepare curricula, not scientific nomenclature codes. Memory cue: “universal biological names require universal rules.”
