A duly registered chemical engineer must be a holder of the following except this.

• A. None of the above
• B. College diploma
• C. Professional Identification Card
• D. Certificate of Registration

Answer: (A)

The essential idea is that professional registration typically requires three elements: evidence of education, licensure, and identification. A college diploma shows the educational prerequisite engineers must have. A certificate of registration is the legal authorization to practice as a professional engineer. A professional identification card provides a portable proof of status for verification in professional settings. Because all three are normally required, there isn’t an extra item among them that can be omitted, so None of the above is the correct choice. If a jurisdiction uses different terminology, the underlying point remains: education, licensure, and identification together establish and demonstrate professional registration.
