Which of the following management risks can make an organization's cloud environment unviable?

Insider trading is a financial crime related to stock markets, not a direct management risk that makes a cloud *environment* unviable.

VM sprawl, characterized by the uncontrolled creation and retention of virtual machines, significantly increases operational costs, consumes unneeded resources, and expands the attack surface. If left unchecked, it can lead to unsustainable expenses, poor performance, and security vulnerabilities, making the cloud environment economically or practically unviable for an organization.

A hostile takeover refers to a change in corporate ownership, which is a business-level risk, not a specific management risk that directly impacts the *viability* of a cloud *environment*.

Improper personnel selection is a human resources risk; while it can indirectly affect cloud operations, it doesn't directly make the *environment* itself unviable in the same way a technical and cost-intensive issue like VM sprawl does.
