Réponse officielle
because of high taxes (taxation without representation)
because the British army stayed in their houses (boarding, quartering)

Explication
Parliament taxed the colonies while giving them no members in it, quartered soldiers in colonial homes and restricted colonial self-government. Those grievances, not any of the alternatives, led to war.
