As it is Chegg policy to answer one question per answer. Hence, I am answering the first question and request you to post the rest of the question individually. Thank you.

a.) Applications that run on standard operating systems and provide VMM features to guest Operating systems:

• This is the use of the Type 1 VMM( Native, Bare Metal) because they are responsible for running directly on the host's hardware to control the hardware and also to manage the guest Operating System accordingly.
• So, in the above case, it satisfies these condition of Type 1 VMM as the application is running on the host's hardware and the features are being provided to the guest Operating system for management purpose.

b.) Operating system like software built to provide virtualization:

• This is also making use of Type 1 VMM(Native, Bare metal) as we can see the software will be running on the host's hardware and the virtualization will be provided to the guest Operating system.

c.) Can provide virtualization-within virtualization:

• This example will be making use of the Type 2 VMM(or hosted) as we can see that it will be running within a conventional operating system environment which will be categorized under the Type 2 VMM.

Hence, these are the types that each of these examples are associated with.
