The correct answer is C .

The typing errors in the options should be corrected as follows:

event.stopPropagation();

The stopPropagation() method is used to stop an event from continuing through the DOM event propagation path.

A click event normally goes through these phases:

Capturing phase → Target phase → Bubbling phase

Because the event listener is attached to the button:

el.addEventListener( " click " , printMessage, false);

the function printMessage receives the click event when the button is clicked. To stop the event from bubbling up to parent elements, the event object should be accepted as a parameter and stopPropagation() should be called inside the event handler.

Corrected code:

< html >

< body >

< div id= " logo " > Hello Logo! < /div >

< button id= " test " > Click me < /button >

< /body >

< script >

function printMessage(event) {

event.stopPropagation();

console.log( ' This is a test message ' );

}

let el = document.getElementById( ' test ' );

el.addEventListener( " click " , printMessage, false);

< /script >

< /html >

Why this is correct:

event.stopPropagation();

prevents the click event from moving upward to ancestor elements after the button’s handler runs.

Why the other options are incorrect:

A and B are incorrect because removeEventListener() is used to remove a previously registered event listener. It does not stop event bubbling for the current event.

D is incorrect because stopPropagation() should be called inside the active event handler that receives the event object. In this case, that function is:

printMessage(event)

Therefore, the verified answer is C .
