how to show questions options together in laravel after explode?

 public function index()
{
    $subCategory = Category::where('status' , 0)->where('parent_id' , '!=' , 0)->get();
    $categories = Category::where(['status' => 0 , 'parent_id' => 0])->get();
    $questions = Question::join('question_options' , 'questions.id','=','question_options.question_id')->where('status' , 0)->get(['questions.*' , 'question_options.options' ]);

    return view('questions')->with(['categories' => $categories , 'subCategory' => $subCategory , 'questions' => $questions]);
}



public function addQuestion(Request $request)
{
    $categoryName = $request->input('category_id');
    $subCategoryName = $request->input('sub_category_id');
    $questionDetail = $request->input('question_detail');
    $questionOptions = $request->input('options');
    $questionAnswer = $request->input('answer');
    $questionType = $request->input('type');
    $validation = Validator::make($request->all(), [
        'category_id' => 'required|max:100',
        'question_detail' => 'required|max:100',
        'options' => 'required|max:100',
        'answer' => 'required|max:100',
        'type' => 'required|max:100',
    ]);
    if ($validation->fails()) {
        return redirect()->back()->with('$error', $validation->errors()->first());
    } else {

        $location = 'images/question_images';
        $questionImg = "";
        $getImage = (new customSlim())->getImages();
        if(count($getImage) > 0){
            $questionImage = $getImage[0];
            $questionImgSave = (new customSlim)->saveFile($questionImage['output']['data'], $questionImage['input']['name'], $location);
            $questionImg = $questionImgSave['name'];
        }

        $question = new Question();
        $question->category_id = $categoryName;
        $question->question_detail = $questionDetail;
        $question->image = ('images/question_images/'. $questionImg);
        $question->option_id = $questionAnswer;
        $question->type = $questionType;
        $saveQuestion = $question->save();
        if($saveQuestion){

            $QuestionoptionsArray = explode(',', $questionOptions);
            foreach($QuestionoptionsArray as $option){
                $Questionoptions = new QuestionOption();
                $Questionoptions->question_id = $question->id;
                $Questionoptions->options = $option;
                $Questionoptions->save();
            }
        }
    }
    if ($saveQuestion) {
        return redirect()->back()->with(Session::flash('alert-success', 'Question Added Successfully!'));
    } else {
        return redirect()->back()->with(Session::flash('alert-danger', 'Failed to Add Question'));
    }
}

The question is how i can show question options together in one line. like (six,eight,five,nine). i have two database one for question and other is for question options where i'm saving question option with explode() along question id. how can i show this?
