I think you can try this :

<div class="form-group" id="group-form-id">
                    <label id="correct_answer" style="color: #00a65a;">
                        @lang('test-results.correct_answer'):
                        <div style="line-height: 8px; padding-top: 5px;">
                            <?php $i=1; ?>
                        @foreach($question->answers->sortBy('order') as $answer)
                                @if($answer->order)

                                <span id="test_span"><br><em style="padding-right: 10px; color: #999;">{{ $i }}.</em>{!! $answer->text !!}</span>
                            <hr style="width: 500%;border-top: 1px solid rgba(238, 238, 238, 0.37);">
                            @endif
                            <?php $i++; ?>
                        @endforeach
                        </div>

Hope this work for you !!!

You can sort the answers collection:

$question->answers->sortBy('order')

Check Laravel Collections

答

In the controller when you return the questions you can use query builders orderBy(order). See this documentation: Laravel Query Builder - Order By
