• Chose B1

  B. Perform stale reads using single-read methods: Stale reads (also known as bounded staleness reads) can execute with lower latency because they can serve data from a timestamp in the recent past and do not have to wait for ongoing writes to be completed. This allows the application to trade off some consistency for lower latency, which is suitable for this scenario.

• Chose B1

  It Should be B. Since the application is more sensitive to latency and less sensitive to consistency performing stale reads is the best choice here. It will provide low latency at the cost of potentially returning stale data.
