Which of the following is NOT considered personal data under GDPR?

Personal data under the General Data Protection Regulation (GDPR) is defined as any information that relates to an identified or identifiable individual. In this context, items like a name, email address, and computer IP address all pertain specifically to individuals. They can be used to identify or track a person, thus falling under the scope of personal data protection provided by GDPR.

The term "business strategy" does not relate to an identifiable individual. Instead, it pertains to a company's operational plans and tactics, which are not associated with any specific person. Consequently, business strategies do not meet the criteria of personal data as defined by GDPR, making it the correct answer to the question regarding what is not considered personal data under this regulation.
