The correct answer is B. AWS Lambda.

Explanation:

AWS Lambda is a serverless compute offering from AWS that allows you to run your code without the need to provision or manage servers. With AWS Lambda, you only pay for the compute time that you consume, making it a cost-effective solution for running small, event-driven applications or for executing individual functions within larger applications.

Here are brief descriptions of the other options:

A. AWS EC2: Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It is not a serverless offering, as it requires you to provision and manage virtual machines (EC2 instances) to run your applications.

C. AWS SNS: Amazon Simple Notification Service (SNS) is a fully managed messaging service that enables you to decouple and scale microservices, distributed systems, and serverless applications. It is not a compute offering, but rather a messaging service.

D. AWS SQS: Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. Like SNS, it is not a compute offering, but rather a messaging service.

In summary, AWS Lambda is the only serverless compute offering among the options provided.
