Selected Answer: B

It's B. Duration – The amount of time that your function code spends processing an event. The billed duration for an invocation is the value of Duration rounded up to the nearest millisecond. https://docs.aws.amazon.com/lambda/latest/dg/monitoring-metrics.html

Selected Answer: B

I choose duration day because I'm pretty sure it's the lambda problem. Integration latency will cover the whole backend response, therefore we are not sure about whether it's the problem of API gateway or lambda.
