Answer: Azure Repos

The correct answer is A: Azure Repos. Azure Repos provides a set of version control tools that you can use to manage your code. It includes both Git and Team Foundation Version Control (TFVC) repositories. Options B (Azure DevTest Labs) and D (Azure Cosmos DB) serve different purposes; B is for creating lab environments, and D is a globally distributed, multi-model database service. Option C (Azure Storage) is for storing data, not specifically for version control.
