The manner in which [triggers](https://xlsform.org/en/#trigger) are defined _in XLSForm_ means that no, you cannot have a **dependent** question being 'triggered' by anything other than a change in a _single_ so-called **antecedent** question [aside, I discuss this limitation, albeit in a difference context, in some detail here: [Spec proposal: expose xforms-value-changed event with odk:setgeopoint action in XLSForm](https://forum.getodk.org/t/spec-proposal-expose-xforms-value-changed-event-with-odk-setgeopoint-action-in-xlsform/48655)]. Which is to say, Question B can only be 'triggered' by a change in Question A, not as you say a change in Question A _or_ C. However, under the covers in raw XForms, there is actually nothing to prevent you performing _multiple_ **xforms-value-changed** event triggered **setvalue** actions - which is bascially what an XLSForm trigger becomes - to accomplish this. That is, you can actually have Question B be recalculated whenever Question A changes **or** when Question C changes (in fact they can even perform completely different calculations!) Have a play with this XForm. It essentially consists of two different types of multi-triggers. The first triggers the same calculation whenever either of two antecedent questions change; basically your "trigger can't be an `or` expression" situation. The second set is a min/max example that readjusts a previously entered value should the min or max then be adjusted.
