Part of the body with a lobe

EAR

This sensory organ helps with balance and is often adorned with jewelry like studs or hoops.

The clue "Part of the body with a lobe" points to the ear because the ear has a visible outer lobe. It’s a straightforward definition—no wordplay or tricks—just naming a body part known for that specific feature. Other body parts have lobes (like the liver or lungs), but "ear" is the most familiar and fits the simple phrasing.
