How are the API implementation, API client, and API consumer combined to invoke and process an API?
A . The API consumer creates an API implementation, which receives API invocations from an API such that they are processed for an API client
B . The API consumer creates an API client which sends API invocations to an API such that they are processed by an API implementation
C . An API client creates an API consumer, which receives API invocation from an API such that they are processed for an API implementation
D . The API client creates an API consumer which sends API invocations to an API such that they are processed by API implementation

Answer: C

Explanation:

The API consumer creates an API client which sends API invocations to an API such that they are processed by an API implementation

This is based on below definitions API client

• An application component • that accesses a service

• by invoking an API of that service – by definition of the term API over HTTP API consumer

• A business role, which is often assigned to an individual

• that develops API clients, i.e., performs the activities necessary for enabling an API client to invoke APIs API implementation

• An application component

• that implements the functionality
