Quizplus · Accepted Answer

Enumerations require unique identifiers to distinguish between the different constants/values represented by the enumeration. Therefore, option A is the correct answer. Option B is incorrect because duplicating identifiers would not be practical and would cause confusion. Options C and D are incorrect because nothing specifies that the identifiers must be lowercase or uppercase letters only, and they are not required to exclude numbers.
