Since they didn't place any guide in the patchnotes which option gives which mount...
Option 1: Study
Outcome: Draculia turns into a normal vampire
Corresponding 7-token reward: Draculia's gift B (Coffin)

Option 2: Work
Outcome: Draculia turns into a normal human
Corresponding 7-token reward: Draculia's gift A (Merchant)

Option 3: Battle
Unlike other options, battle option gives you 200 Halloween points after clearing the stage.
Outcome: Draculia turns into a Vampire King (wait, I though Draculia's a she...)
Corresponding 7-token reward: Draculia's gift C (Throne)

Additional notes:
- You can get the quest again after completing it (basically you can repeat it for the other types of token since you need only 7 of a single kind to get the quest), making it possible to collect them all
- If you want to check how much tokens you already have of each type, you can see them in Inventory->Quest tab
