Answer:

CO - Appears furthest downfield

Explanation:

The carbon - 13 NMR shows the position of the carbon atoms on the spectroscopy.

The carbon atoms attached to the electronegative elements appear further downfield. The carbon atom attached to the oxygen atom (CO) appears furthest away due to the presence of the oxygen atom.
