What is wrong with this FastAPI startup event code using databases library?

@app.on_event("startup")
async def startup():
    database.connect()

Adatabase.connect() is not a valid method

BStartup event should be synchronous

CMissing await before database.connect()

Ddatabase variable is not defined

Step-by-Step Solution

Solution:

Step 1: Check async method call
The connect() method is asynchronous and requires await when called inside an async function.
Step 2: Identify missing await
The code calls database.connect() without await, which will cause a coroutine to be created but not executed.
Final Answer:
Missing await before database.connect() -> Option C
Quick Check:
Async connect needs await = B [OK]

Quick Trick: Await async connect in startup event [OK]
