Box 1: will have no access
The IP 193.77.134.1 does not have access on the SAS since this IP falls outside of the allowed IP address range for SAS. Hence "will have no access" is correct.
Box 2: will be prompted for credentials
The net use command is used to connect to file shares.To mount an Azure file share, you will need the primary (or secondary) storage key. SAS keys are not currently supported for mounting. Based on the provided SAS exhibit, IP address is an allowed IP and also on given date SAS is active, but account storage key is must to have to run the "net use" command , which is not provided in the question. Hence "will be prompted for credentials" is correct option for this.

Cost analysis: Correct Option
In cost analysis blade of Azure, you can see all the detail for custom time span. You can use this to determine expenditure of last few day, weeks, and month. Below options are available in Cost analysis blade for filtering information by time span: last 7 days, last 30 days, and custom date range. Choosing the first option (last 7 days) auditors can view the costs by time span.
Cost analysis shows data for the current month by default. Use the date selector to switch to common date ranges quickly. Examples include the last seven days, the last month, the current year, or a custom date range. Pay-as-you-go subscriptions also include date ranges based on your billing period, which isn't bound to the calendar month, like the current billing period or last invoice. Use the <PREVIOUS and NEXT> links at the top of the menu to jump to the previous or next period, respectively. For example, <PREVIOUS will switch from the Last 7 days to 8-14 days ago or 15-21 days ago.

Invoice: Incorrect Option
Invoices can only be used for past billing periods not for current billing period, i.e. if your requirement is to know the last week's cost then that also not filled by invoices because Azure generates invoice at the end of the month. Even though Invoices have custom timespan, but when you put in dates for a week, the pane would be empty. Below is from Microsoft document:

Resource Provider: Incorrect Option
When deploying resources, you frequently need to retrieve information about the resource providers and types. For example, if you want to store keys and secrets, you work with the Microsoft.KeyVault resource provider. This resource provider offers a resource type called vaults for creating the key vault. This is not useful for reviewing all Azure costs from the past week which is required for audit.
Payment method: Incorrect Option
Payment methods is not useful for reviewing all Azure costs from the past week which is required for audit.

Ensure port 445 is open: The SMB protocol requires TCP port 445 to be open; connections will fail if port 445 is blocked.

Explanation

Read only and Delete lock won't prevent you from moving resources in different resource groups. It will prevent you to do the operations in the resource group where the resources are there.
So the correct answer should be
RG1 --> RG2 = IP1, vnet1 and storage1
RG2 --> RG1 = IP2, vnet2 and storage2
