Answer-first summary for fast verification
Answer: AWS Lambda
The correct answer is C, AWS Lambda. AWS Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you. In this scenario, the Python application can be triggered by an event (new images being stored in an S3 bucket) and then process the images by adding a watermark. This service requires minimal operational overhead as it scales automatically and you only pay for the compute time you consume. Amazon EC2 (A) would require managing servers, AWS Code Deploy (B) is for deploying code to various compute services, and Amazon Lightsail (D) is more suited for simpler applications with a need for more direct control over the underlying server.
