According to the UK GDPR, the processing of personal data must be lawful, fair and transparent1. Lawfulness means that there must be a valid legal basis for processing personal data, such as consent, contract, legal obligation, vital interests, public task or legitimate interests1. Fairness means that the processing must not be detrimental, unexpected or misleading to the individuals concerned1. Transparency means that the individuals must be informed about how their data is used, who it is shared with, what rights they have and how they can exercise them1. Therefore, the sentence that best summarizes these concepts is option A, which states that fairness and transparency refer to the communication of key information before collecting data; lawfulness refers to compliance with government regulations.
