A. B. C. D.A
Azure Data Lake Storage Gen2 implements an access control model that supports both Azure role-based access control (Azure RBAC) and POSIX-like access control lists
(ACLs).
https://docs.microsoft.com/en-us/azure/storage/blobs/data-lake-storage-access-controlThe storage solution that supports access control lists (ACLs) at the file and folder level is Azure Data Lake Storage (Option A).
Azure Data Lake Storage is an enterprise-wide hyper-scale repository for big data analytic workloads. It is a highly scalable and secure data lake that allows storage and analysis of structured, semi-structured, and unstructured data. It provides the capability to store and analyze data at petabyte scale.
Access Control Lists (ACLs) allow you to control who can access your files and directories in Azure Data Lake Storage. ACLs define permissions for users and groups at the file or folder level. ACLs are used to restrict unauthorized access to data in the storage account.
Azure Blob storage (Option C) provides shared access signatures (SAS) that allow you to control access to containers and blobs at a granular level, but it does not support ACLs at the file and folder level.
Azure Queue storage (Option B) is a messaging service used to store and retrieve messages. It does not support ACLs.
Azure Cosmos DB (Option D) is a globally distributed, multi-model database service. It provides fine-grained access control at the document level, but it does not support ACLs at the file and folder level.
Therefore, the correct answer is Option A, Azure Data Lake Storage.
