The correct answer is B and C. I was suspicious about C at first (provisioned concurrency). Because I was thinking it would only affect the number of concurrent requests but not the start latency. But I am convinced after reading this: https://docs.aws.amazon.com/lambda/latest/dg/provisioned-concurrency.html
