WaleedAhmedSulais-6914 Looks like your quota is not enough to select the virtual machines.
Since you are using student subscription, there are certain limitations and restrictions, including limited access to certain virtual machine sizes.
First check the available quota from Azure Portal.
Goto Azure Portal -> Search Quota -> select Azure Machine Learning
If quota is not available for any of the VMs then you must request for more quota.
See how to Manage and increase quotas and limits for resources with Azure Machine Learning
If you are not able to increase the quota on a student subscription, please contact customer service at any time so that we can adjust your limits appropriately.
You must upgrade your Azure for Students Starter subscription to a Pay-As-You-Go subscription to increase your quotas or limits.
For more information, see Upgrade your Azure Free Trial subscription to a Pay-As-You-Go subscription
Do let me know if that helps or have any other queries.
