Attach or sync in one to many relation laravel

Question Model:


Option Model:


Question Controller

$question = new Question;
$question->question = 'Question';
$question->options()->attach(['option1', 'option2', 'option3', 'option4']);

I'm trying to attach the options data, but it says error "Call to undefined method Illuminate\Database\Query\Builder::attach()"

How to attach and sync that in the right way?

    Relationship one to many does not have method attach().attach() method working only for relationship ManytoMany. You can just use id one of your model.
