Final answer:
A free Azure account does not offer an unlimited number of web apps; it provides a limited number within the constraints of the free tier supported by Azure App Service.
Step-by-step explanation:
The statement that an Azure free account can contain an unlimited number of web apps is false. When you sign up for an Azure free account, you initially receive a limited amount of free services for 12 months. After the first month, you only keep limited access to a subset of free services. The number of web apps you can host in Azure for free is limited by the Azure App Service Free tier, which allows you to run a certain number of web apps with some limitations on size, features, and computation resources. If you need to run more web apps or require more capabilities and resources, you will need to upgrade to a paid plan.
