while ($donnees = $req->fetch())
{
$questionid = $donnees['Questionid'];

$insertArray = array(
[0]=> array(

['Questionid'] =>$questionid,
['Options'] => $_POST['Option_1'],
),

[1]=> array(
['Questionid'] =>$questionid,
['Options'] => $_POST['Option_2'],
),

[2]=> array(
['Questionid'] =>$questionid,
['Options'] => $_POST['Option_3'],
),

[3]=> array(
['Questionid'] =>$questionid,
['Options'] => $_POST['Option_4'],
));
if (!empty($_POST['Option_1']) && !empty($_POST['Option_2']) && !empty($_POST['Option_3']) && !empty($_POST['Option_4']))
{
foreach ($insertArray as $key => $value) {
$db->exec('INSERT INTO answerproposal(Questionid,Options) VALUES(\'$value['Questionid']\', \'$value['Options']\')');

try using this array

$insertArray =
 array(
 1=>array("Questionid"=>$questionid,"Options"=>$_POST['Option_1']),
 2=>array("Questionid"=>$questionid,"Options"=>$_POST['Option_2']),
 3=>array("Questionid"=>$questionid,"Options"=>$_POST['Option_3']),
 4=>array("Questionid"=>$questionid,"Options"=>$_POST['Option_4']));

and on foreach remove single quotes use it like this i.e

$value[Questionid]
