<option <?php if ($row['status'] == 0) { ?> selected <?php } ?> value="0">In process</option>
<option <?php if ($row['status'] == 1) { ?> selected <?php } ?> value="1">Completed</option>
</select>

This is normally what I like to do(this goes intto your controller):
// Select Categories
$categories_options = array();
$categories_options[0] = 'Select Categories';
$categories_list = $this->Terms_model->get_list();
foreach($categories_list as $cat){
$categories_options[$cat->term_id] = $cat->title;
}
$data['categories_options'] = $categories_options;
Assuming that your passing a $data variable to your view, you will be able to display it like this:
<!-- Post Categories -->
<?php
$data = array(
'class' => 'form-control js-example-basic-multiple',
'value' => set_value('categories'),
'multiple' => 'multiple',
);
?>
<div class="form-group">
<?= form_label('Categories','categories'); ?>
<?= form_dropdown('categories[]', $categories_options, 0, $data); ?>
</div>
and then to edit it(a different view):
<?php
$options = array(
'' => 'Please select an option',
'0' => 'In process',
'1' => 'Completed',
);
$data = array('class' => 'form-control');
?>
<div class="form-group">
<?= form_label('Status', 'status'); ?>
<?= form_dropdown('status', $options, $item->status, $data); ?>
</div>
Obviously you will need to change more stuff but I'm sure it will give you a better idea and approach.

Try something like this:
$status = ($row['status']) ? 'selected' : '';
echo <<<END
<option value="0" $status>In process</option>
<option value="1" $status>Completed</option>
END;

Using class... most of dropdown components uses active class to definy the first element on dropdown, so just put it on which element you want and will do the trick
