The Virtual Network has no address space which is relative to 192.168.1.0/24 as per the powershell output given in the Exhibit.
Hence first, you need to add an address space as shown below.

After you save the address space, create a new subnet with the address space and then ensure the VM is put in the new subnet Option A is incorrect since the network interface can only receive an address from 10.2.0.0/24 as per the powershell output given in the Exhibit.
Option B is incorrect since you need to add the address space 192.168.1.0/24 before adding the subnet Options D and E are incorrect since you need to add the address space and subnet and not delete the address space and subnet
