Select ID and post_title using WP_Query using post_fields filter

My Wp_query Is followin

$args = array(
    'post_type' => DR_QUES_POST_TYPE_QUESTIONNAIRE,
    'posts_per_page' => -1,
    'post_status' => 'publish',
    'tax_query' => array(
        array(
            'taxonomy' => 'course-data',
            'field'    => 'slug',
            'terms'    => $name
        ),
    ),
);
$query = new WP_Query( $args );

I want you fetch only Post ID and post_title fields using posts_fields filter.

If any suggestion then give me idea.
