To ensure that NGINX is available on all the virtual machines after they are deployed in a virtual machine scale set, you should use the Azure Custom Script Extension.

Option A, the Publish-AzVMDscConfiguration cmdlet, is used to publish PowerShell Desired State Configuration (DSC) resources to an Azure Automation account, which is used to manage configuration settings of virtual machines. However, it does not address the requirement of installing NGINX.

Option B, Azure Application Insights, is a tool for monitoring and analyzing application performance and usage. While it can help you monitor the performance of your virtual machines, it does not address the requirement of installing NGINX.

Option C, Azure Custom Script Extension, allows you to run custom scripts on a virtual machine after it has been deployed. You can use this extension to install NGINX on all virtual machines in a virtual machine scale set. You can create a script that installs NGINX, upload it to Azure Storage, and then use the Azure Custom Script Extension to run the script on all virtual machines in the scale set.

Option D, the New-AzConfigurationAssignement cmdlet, is used to create a new Azure Policy assignment. Azure Policy is used to enforce organizational standards and compliance in Azure resources. It does not address the requirement of installing NGINX.

Therefore, the correct answer is C, Azure Custom Script Extension.
