Final answer:
An organization needs to appoint a Data Protection Officer (DPO) under three circumstances according to GDPR: systematic large-scale monitoring of data subjects, large-scale processing of special data categories, or if the controller is a public authority. So, options A, B, and C all necessitate a DPO.
Step-by-step explanation:
According to the General Data Protection Regulation (GDPR), there are three circumstances under which an organization must appoint a Data Protection Officer (DPO):
- If the core activities of the controller or processor include regular and systematic monitoring of data subjects on a large scale which is option A;
- If the core activities of the controller or processor consist of large scale processing of special categories of data or data relating to criminal convictions which is option B;
- Finally, if the controller is a public authority or body (except for courts acting in their judicial capacity) which is option C.
Therefore, all the choices provided (A, B, and C) require the appointment of a DPO.
