A: The result of the stressor..
The word "victim" would qualify as a trigger based on what you're written. (In the same way as the OP used "You are so sweet" as a trigger phrase.Sorry for using the term incorrectly.
My therapist uses the term when he sees me get keyed up and we can't figure out the specific reason but we know it's a hot button. FOR instance: I spoke about being referred to as a victim as a "trigger" because it is what my therapist called it. I don't know what specifically in my past makes me have such an extreme reaction. By definition it should probably be called a stressor.
