This intriguing question comes from Crafting the Public API topic in division Parsing, Benchmarking and Logging of JavaScript

Answer 1

The correct answer is (c) 3

Explanation: BaseFieldType provides three events that you can latch code onto:

onBeforeSave() : Called right before a field is saved.

onAfterSave() : Called right after a field is saved, and $this->model->id is set.

onAfterElementSave() : Called right after an element is saved, and $this->element->id is set.
