Which of the following is NOT a requirement concerning content published on the EUROPA website?

The selection indicating "Cookies not requiring informed consent" accurately identifies a requirement that is not applicable to the EUROPA website. To elaborate, the EU's regulations stipulate that if personal data is involved, websites must obtain informed consent from users before placing cookies on their devices. This ensures transparency and gives users control over their data and privacy, making it essential for compliance with data protection laws.

On the other hand, the other options represent legitimate requirements for content published on the EUROPA website. These include the necessity for cookies to have informed consent, ensuring that all users can access content regardless of ability, and performing quality checks on the content to maintain high standards of reliability and accuracy. Thus, the focus on informed consent regarding cookies aligns with the overarching privacy principles guiding internet usage in the EU.
