This would require you to draw the Electron Dot Diagram for the molecule. You will see in doing so that the two hydrogens are connected to the carbon using a single bond each and that the oxygen is joined to the carbon using a double bond. Each single bond is 2 electrons and each double bond is 4. 2x2 + 4 = 8 bonding electrons. The answer is D
