Which of the following is not required to be included in information provided to data subjects?

The correct answer is that the controller's legitimate interest is not specifically required to be included in the information provided to data subjects under GDPR. While the General Data Protection Regulation mandates that data subjects must be informed about various elements concerning their personal data, the focus is often on the overall purpose of processing rather than an emphasis on the specific lawful basis for processing.

Under Article 13 of the GDPR, when personal data is collected from data subjects, several pieces of information must be provided, including the identity of the controller, the purposes for processing the data, and the rights available to the data subjects regarding their information. However, the legitimate interests pursued by the controller is a different aspect and, while it can be relevant depending on the situation, it is not explicitly required in the same way that the other elements are under the GDPR framework.

Therefore, understanding which details are essential according to the regulations helps to clarify that while accountability and transparency are key principles of data protection, not all elements of legal basis are mandated to be communicated unless they pertain to the specific rights and positional obligations of the data subjects.
