A. B. C. D.B.
The correct answer for this question is B. self-service.
The cloud model offers a self-service approach to computing resources that can be dynamically provisioned and de-provisioned based on demand. This is particularly beneficial for companies with a variable number of employees, as it allows them to scale their IT infrastructure up or down as needed without having to make significant upfront investments in hardware and software.
Self-service also enables employees to access and use computing resources on their own, without having to go through a centralized IT department. This can be especially useful for companies with remote or mobile workers who need access to IT resources from different locations.
While multifactor authentication, subscription services, and collaboration are all potential benefits of the cloud model, they are not specifically related to the needs of a company with a variable number of employees. Multifactor authentication can improve security, subscription services can provide cost predictability, and collaboration tools can enhance productivity, but they do not directly address the issue of dynamic scalability that is particularly relevant to companies with fluctuating workforce sizes.
