Name a core GDPR principle and its implication for data processing?

• A. Data can be processed without consent under any circumstance.
• B. De-identification removes all obligations.
• C. Data retention is optional.
• D. Lawfulness, fairness, and transparency; processors must have lawful basis, process fairly, and inform data subjects about processing.

Answer: (D)

Understanding GDPR means recognizing how data processing must be grounded in a valid basis, carried out fairly, and done with clear notice to the people involved. The strongest principle here is that processing must have a lawful basis, be fair in its handling, and be transparent about what is being done. A lawful basis is the reason you’re allowed to process someone’s data. There are several bases you can rely on—such as consent, contract, legal obligation, vital interests, public task, or legitimate interests. Processing isn’t allowed just because you find it convenient; you need one of these legitimate foundations and you must meet the associated safeguards. Fairness means handling data in a way that respects individuals’ reasonable expectations and avoids misleading or intrusive practices. Transparency means telling data subjects about what you’re doing with their data, why, who you share it with, how long you’ll keep it, and what rights they have, typically through a privacy notice and ongoing communications. This is why the correct option is the best answer: it emphasizes lawfulness, fair processing, and transparency, including the need for a lawful basis and clear information to data subjects. Why the other statements don’t fit: data processing isn’t allowed without a lawful basis under any circumstance, because there must be a legal reason to process. De-identification does not erase all obligations; it reduces risk but does not remove the duties of data protection, and if re-identification is possible, obligations still apply. Data retention isn’t optional; you must retain data only as long as necessary for the purpose and in line with retention schedules and policies.
