In English, the four words "甲乙丙丁" are typically translated as "A, B, C, D." These are the first four letters of the English alphabet and are often used to label items in a list or to refer to multiple choices in a test or quiz. For example, a teacher might write "Please choose the correct answer from the following options: (A) 甲, (B) 乙, (C) 丙, (D) 丁." In this case, the words "甲乙丙丁" would simply be translated as "A, B, C, D" in English.
