B is the correct answer.
Option A suggests that the organization is at fault because it did not fix all identified vulnerabilities. However, in the context of limited resources, organizations often need to prioritize and allocate their resources strategically.
In the scenario described, the organization decided to fix the most severe vulnerability based on its understanding and resource limitations. While it's true that addressing all vulnerabilities would be ideal, practical constraints may prevent this. Therefore, placing the entire blame on the organization may not be fair.
Option B is a more balanced choice, indicating that both the organization and John share responsibility. This acknowledges that the organization made a decision based on its constraints, but it also suggests that John, as the ethical hacker, has a role in emphasizing the importance of addressing all vulnerabilities and the potential risks associated with leaving some unpatched.
