Explanation

Using S3 event notifications to trigger AWS Lambda for file processing is a cost-effective and serverless solution. Lambda scales automatically with upload volume, and processing each file takes less than 5 seconds, fitting within Lambda's execution time. Option A:AWS AppSync is designed for GraphQL APIs and is not suitable for file processing. Option C:Kinesis is overkill and more expensive for this use case. Option D:Running an EC2 instance incurs ongoing costs and is less flexible compared to Lambda.
