The capacitor must fire because without it there is not enough current through the alarm to set it of. Well, we know that our voltage is constant since we have a 9V battery powering it. This means that option 1 doesn't apply. However, we have a variable R in the path that exists across the capacitor (i.e. the "discharge" path).
