Answer:
1. C.operating system
2. A.applications 
Explanation:
1. The Iaas is the infrastructure as a service, and storage, server, and network are the infrastructures. However, the Operating System is the platform, and hence it is the correct option for the first blank. We need to understand the exact meaning of the IaaS, PaaS and the SaaS as well as MaaS, to better understand cloud computing.
2. In the second case, we have been asked about the option that is not being covered by the PaaS, and Paas stands for the platform as a service. And the interface, storage, and virtualization is the platform whereas the Applications is an example of software. And it is being managed by SaaS, Hence, the correct option is A. Applications.
