Why Not Other Options?

A. Roll-up summary fields can cause the parent record to go through Save:

When a roll-up summary field on a parent object (like Account) is updated due to changes in child records (like Branch), the parent record (Account) is implicitly saved again.

This can result in the execution of the trigger on the parent object. Developers must consider this behavior to avoid unintended recursion or infinite loops.
