Which of the following scenarios presents the GREATEST risk of noncompliance with data privacy best practices?

Making data available to a larger audience of customers may introduce security or privacy risks depending on the data type and controls, but it is not inherently a non-compliance risk if proper consent and anonymization are in place.

Data not being disposed of according to retention policy is a compliance risk, but often less fundamental than misusing data against a data subject's explicit wishes.

Personal data not being de-identified properly is a significant privacy risk that can lead to re-identification, but it is a technical failure in data handling, whereas using data without consent is a violation of fundamental rights and principles.

Using personal data beyond the scope of its original collection purpose or without explicit consent (opt-in) directly violates fundamental data privacy principles like purpose limitation and consent requirements found in regulations such as GDPR, leading to severe noncompliance risks.
