Adaface Sample FastAPI Questions

Given the following FastAPI code snippet, analyze the structure and identify potential issues or inefficiencies related to async programming.

Which of the following is a valid observation about the provided code? 
            
            A: The use of `requests` in `read_async_data` is appropriate for async execution. 
            B: Both endpoints are efficient and correctly implemented for their purpose. 
            C: The `read_async_data` function has a blocking call that should be handled asynchronously. 
            D: The `HTTPException` handling is incorrect in the context of the `read_async_data` function. 
            E: The lack of JSON responses in the endpoints will cause issues in FastAPI. 
            F: The endpoints will work correctly without any modifications.

You have a FastAPI application with a simple endpoint that returns user information in JSON format. You need to write a test using pytest and HTTPX to verify the correct status code and response structure.
            
            Here's the pseudo code for the FastAPI endpoint:
            

As a senior developer, implement a test using pytest and HTTPX that checks:
            1. The endpoint returns a status code of 200.
            2. The response body contains the correct user_id passed.
            3. The email field follows a valid email format.
            4. Use the HTTPX AsyncClient feature to perform an asynchronous test call.
            
            Which of the following correctly represents a partial implementation of this test?
