Provides single digit millisecond read and write latency under 8 ms at the 99th percentile worldwide is correct because it directly addresses the requirement for a globally distributed key value store that needs very low latency.

The Provides single digit millisecond read and write latency under 8 ms at the 99th percentile worldwide statement reflects the performance characteristics of the Cosmos DB Table API which is engineered for global distribution and offers multi region replication and low tail latency for reads and writes.

Service level agreement of 99.995% availability is incorrect because an availability SLA does not guarantee the single digit millisecond latency under global load and the question is specifically about latency rather than uptime.

Cloud Bigtable is incorrect because it is a Google Cloud product and not an Azure Table Storage or Cosmos DB option, so it does not answer why one would pick Cosmos DB Table API over Azure Table Storage.

SDKs available for many programming languages and platforms is incorrect because while broad SDK support is useful it is not the primary reason to choose a service when the requirement is very low, worldwide latency.
