You need to specify a value in your option tag. However, it is not safe to let the user specify the script to run. So you you should examine the values from the form in your PHP code and decide where to send the user.

<?php
    $lang=$_REQUEST['language'];

    switch ($lang) {
        case 'english':
            $page = 'english.php';
            break;
        case 'hindi':
            $page = 'hindi.php';
            break;    
        default:
            $page = null;
    }

    if ($page) {
        header("Location: ".$_POST['language']);
        exit;
    }

?>

<form method="post">
    <select name="language">
        <option value="">select one</option>
        <option value="english">English</option>
        <option value="hindi">Hindi</option>
    </select>
</form>
