Foreach for dropdown select box in html

I am trying get data in dropdown select box with html edit form

debug output of $countries as below :

array:1 [▼
  1 => "India"
]

This is my HTML code for dropdown:

                        <div class="col-md-6 mb-3 form-group">
                            Country:<select name="country_id" id="country" class="form-control " onchange="myfunc()" >
                                <option value="">Select</option>
                                @foreach($countries as  $key=>$val )
                                    <option value=""></option>
                                @endforeach
                            </select>
                        </div>

What should be <option value="">?
