The correct answer is D. AWS serverless computing, particularly with services like AWS Lambda, abstracts the underlying infrastructure from developers. This means that AWS handles server provisioning, scaling, and maintenance, which allows developers to focus solely on writing code for their applications. This eliminates the need for manual server management, patching, and monitoring, reducing operational overhead and enabling developers to be more productive. While AWS does manage security and provides monitoring and logging tools, the primary benefit highlighted in the question is the offloading of infrastructure management to AWS.
