Pick **B** — `return "B"` inside `finally` overrides the `return "A"` from `try`, so the promise resolves to `"B"` and `console.log` prints `B`.

Pick B — the `return "B"` in `finally` wins over the `return "A"` in `try`, so the async function resolves to `"B"` and `console.log` prints B.

JS Quiz answer: Option 2 (B).

Correct choice: B

Why:  
A `return` in `finally` overrides a previous `return` from `try`. The promise resolves to `B`, so the log is just `B`.

Yeah, it reads nice, but `finally` is a little trapdoor—if you `return` in there it’ll override whatever the `try`/`catch` was going to return, so you can accidentally swallow the “real” result.

I’ve had this bite me in UI code where the “cleanup” path quietly becomes the output. I try to keep `finally` to side effects only—flip `isLoading` off, clear a timer, abort a request—because a `return` in there turns the try/catch result into decoration.
