When you upload a private key certificate to an Azure App Service, it is accessible only to other web apps that are within the same App Service plan, resource group, region, and operating system. In this case, Cert1.pfx is uploaded to App1, which is in RG1, East US, running on Windows, under App Service plan ASP1. Therefore, only App1 can use the certificate because App2, App3, and App4 differ by operating system, location, or App Service plan.
I would go with as as per below explanation After you add a private certificate to an app, the certificate is stored in a deployment unit that's bound to the App Service plan's resource group, region, and operating system combination, internally called a webspace. That way, the certificate is accessible to other apps in the same resource group, region, and OS combination. Private certificates uploaded or imported to App Service are shared with App Services in the same deployment unit.

Sorry missed the answer: it would be A

Store certificate in Azure Key Vault: make sure to use the same subscription and resource group as your App Service app. For that reason only App1 and App2 can use Certificate. https://learn.microsoft.com/en-us/azure/app-service/configure-ssl-app-service-certificate?tabs=portal
Why not A?
When you upload a certificate to App Service, it's stored in the App Service instance's Key Vault. Key Vault is a global service in Azure, meaning it can be accessed from different regions.
