Two requests are independent. Which form starts both before waiting and preserves both results?

1. `const [user, prefs] = await Promise.all([fetchUser(), fetchPrefs()])`
2. `const user = await fetchUser(); const prefs = await fetchPrefs()`
3. `const [user, prefs] = await Promise.race([fetchUser(), fetchPrefs()])`
