Should be A (Table API) and E (Cassandra API). Table API is the best solution for key-value model.

Azure CosmosDB table API is a key-value storage hosted in the cloud. It's a part of Azure Cosmos DB, that is Microsoft's multi-model database. It's a globally distributed, low latency, high throughput solution with client SDKs available for . NET, Java, Python, and Node. So Answer will be A and E

I think it should be MongoDB, since it uses key-value (which is the json format in document). but not storing the key-value pairs(then should be Table API)

It should be D and E. Before Azure Cosmos DB existed, Redis or the Table API might have been a good fit for this kind of data; however, Core (SQL) API is now the better choice, as it offers a richer query experience, with improved indexing over the Table API.
