The explanation section of multiple choice questions is shown once an alternative is selected and submitted. Although it is an optional section when creating questions, it is highly recommended that most questions have an explanation. It is an opportunity not only to explain why the correct answer is correct and in some ways more importantly, why the distractors are incorrect.
Generally, begin by explaining why the correct answer is correct, and then move on to explaining why the distractors are incorrect.
The explanation is also the correct place to attributing an image (see image preparation for further details) or the author of the original question if you have duplicated yours and adapted it.
Don't forget, though, that questions must be original and must not be copied from other texts or from memory (recall questions) from exams.
