   A startup is building a serverless application that processes user uploads. Each upload triggers a Lambda function that resizes an image and stores it in Amazon S3. The function currently has a 512 MB memory setting and completes in about 2 seconds. The startup wants to reduce the cost of running the function while maintaining performance. What should the startup do?

   • ADecrease the Lambda memory setting to 128 MB to reduce cost, even if the function takes longer to complete.
   • BKeep the memory setting at 512 MB and use a provisioned concurrency configuration to reduce cold starts.
   • CIncrease the Lambda memory setting to 1024 MB to reduce execution time, which may lower cost because Lambda bills per millisecond of execution.
   • DMove the image resizing logic to an EC2 instance to have more control over CPU and memory.
