Final answer:
The Supervisory Appraiser is responsible for understanding the AQB minimum requirements for both their own role and that of the Trainee Appraisers they supervise.
Step-by-step explanation:
The correct answer is C) Both Supervisory Appraisers and Trainee Appraisers. Supervisory Appraisers are responsible for understanding the minimum requirements set by the Appraiser Qualifications Board (AQB) for not only themselves but also for those they are supervising, which would be the Trainee Appraisers. This understanding is crucial in providing appropriate training and ensuring that the practices adhere to the professional standards required by the AQB.
Supervisory Appraisers must know how to effectively guide the Trainee Appraisers in their charge, which includes overseeing their work and providing feedback in line with AQB standards. Furthermore, they should be well-versed with the AQB guidelines so that they can be capable teachers and ensure that their trainees are ready to meet the industry's professional demands.
