Question

in a serverless situation, you pay only when your code is running on what? when your codes not running, you dont pay anything.
a ○ subscription
b ○ iot edge
c ○ app service
d ○ vm

Explanation:

In serverless computing, App Service (like Azure App Service in a serverless context) allows you to pay only when your code runs. Subscription is a billing/access model, IoT Edge is for edge computing, and VM (Virtual Machine) is not serverless as you pay for VM runtime even when code isn't running. So the correct option is C.

Answer:

C. App Service
