Which characteristic of serverless computing enables developers to quickly deploy application code?
A . Uploading cloud service autoscaling services to deploy more virtual machines to run their application code based on user demand
B. Uploading the application code itself, without having to provision a full container image or any OS virtual machine components
C. Using cloud service spot pricing to reduce the cost of using virtual machines to run their application code
D. Using Container as a Service (CaaS) to deploy application containers to run their code.

Answer: B

Explanation:

"In serverless apps, the developer uploads only the app package itself, without a full container image or any OS components. The platform dynamically packages it into an image, runs the image in a container, and (if needed) instantiates the underlying host OS and VM and the hardware required to run them."
