Final answer:
The question asks which option is not a standard used in E-Commerce. The correct answer is C.SET, but it must be noted that SET is an actual standard, just potentially outdated. EDI, XML, and X12 are all actively used standards for E-Commerce data exchange.
Step-by-step explanation:
The question is asking which of the following is NOT a standard used in E-Commerce: A.EDI, B.XML, C.SET, D.X12. The correct answer is C.SET (Secure Electronic Transaction), as it is indeed a standard that was developed to ensure secure electronic transactions, specifically for credit card payments.
However, if the question implies which is not commonly used today, then SET could be considered outdated as it has been largely replaced by other security protocols.
EDI (Electronic Data Interchange), XML (eXtensible Markup Language), and X12 are all widely used standards in electronic data interchange within E-Commerce for facilitating the exchange of business documents and data.The correct answer is XML. XML stands for Extensible Markup Language, which is a standard used in E-Commerce for structuring and organizing data.
EDI (Electronic Data Interchange), X12, and SET (Secure Electronic Transaction) are all widely accepted standards used in E-Commerce. However, XML is not a standard used in E-Commerce but rather a format that can be used to represent E-Commerce data.
