Avoidance halts the business process, mitigation entails using controls to reduce risk, acceptance involves taking on the risk, and transference usually involves insurance.

Explanation:
Cloud services make exclusive use of virtualization, and systems change over time, including the addition, subtraction, and reimaging of virtual machines. It is extremely unlikely that the exact same virtual machines and images used in a previous audit would still be in use or even available for a later audit, making the tracking of changes over time extremely difficult, or even impossible. Elasticity refers to the ability to add and remove resources from a system or service to meet current demand, and although it plays a factor in making the tracking of virtual machines very difficult over time, it is not the best answer in this case.
Resource pooling pertains to a cloud environment sharing a large amount of resources between different customers and services. Portability refers to the ability to move systems or services easily between different cloud providers.

With data anonymization, data is manipulated in such a way so as to prevent the identification of an individual through various data objects, and is often used in conjunction with other concepts such as masking.
