You need to define Service Level Objectives (SLOs) for a high-traffic multi-region web application. Customers expect the application to always be available and have fast response times. Customers are currently happy with the application performance and availability. Based on current measurement, you observe that the 90th percentile of latency is 120ms and the 95th percentile of latency is 275ms over a 28-day window. What latency SLO would you recommend to the team to publish?

• A.90th percentile - 100ms
  95th percentile - 250ms
• B.90th percentile - 120ms
  95th percentile - 275ms
• C.90th percentile - 150ms
  95th percentile - 300ms
• D.90th percentile - 250ms
  95th percentile - 400ms
