In Java, variable names must begin with a letter (A-Z or a-z), currency character ($), or an underscore (_). They cannot start with a digit, and special characters like % are not allowed within the variable name. Therefore, "empName_", "addressLine1", and "DISCOUNT" are valid variable names, making option D correct.
