I want echo checked

Without see your controller code I would say that $data['Stake_Holder'] should be $Stake_Holder

What did you Try? What did you Get? What did you Expect?

Check that you've passed $data in the view:

PHP Code:

$this->load->view('viewfile', ['data' => $data]); 


<input type="checkbox" name="accept_terms_checkbox" value="Accept TOS" <?php echo set_checkbox('accept_terms_checkbox', 'Accept TOS'); ?> /> Accept Terms of Services

<input type="checkbox" name="M0140" value="1"  <?php echo ($result->M0140== "1" ) ? "checked" : set_checkbox('M0140, '1',$result->M0140== "1"); ?> size="1">

I think you have to try this...
