Final answer:
ATC personnel must maintain current annual physicals in accordance with FAA Regulations, which is the correct answer to the first part of the student's query. The exact appendix for document retention is not determinable from the provided information.
Step-by-step explanation:
The question is related to the required physical and medical standards for Air Traffic Control (ATC) personnel. When the question asks about where ATC personnel shall maintain a current annual physical in accordance with specified standards, the correct answer is: b) FAA Regulations. The Federal Aviation Administration (FAA) regulates all civil aviation, including the medical requirements for ATC personnel.
As for the location where the retention of these documents can be found, the question does not provide enough information to confidently determine the correct appendix. Usually, such details would be found in the same set of regulations or an official ATC Handbook, but without further context or documentation, one could only speculate on the exact appendix. Therefore, I can only provide a confident answer to the first part of the question.
