Final answer:
To be considered open data, databases must provide rights for the data to be redistributed. Open data is accessible, modifiable, and shareable by anyone, unlike private data that needs protection. Option b is the answer.
Step-by-step explanation:
In order to be considered open data, databases must provide access rights so that they can be B. redistributed. Open data implies that the information can be freely used, reused, and redistributed by anyone. This includes the right for anyone to access, modify, and share the data for any purpose, subject to requirements that preserve provenance and openness. This contrasts with data that must remain private or confidential, such as personal, financial, or medical information, which individuals and organizations have a vested interest in protecting to ensure privacy and security.
People indeed require privacy for personal, financial, and medical details. Furthermore, businesses require security in their operations and governments need to maintain national security by safeguarding sensitive information. However, the concept of open data is aligned with enabling access and redistribution, rather than protecting such private or sensitive information.
