Step 3. Explanation of incorrect options 

Option b is incorrect because ADP (Adenosine diphosphate) is not the energy currency of the cell.

Option c is incorrect because AMP (Adenosine monophosphate) is not the energy currency used by cells.

Option d is incorrect because adenosine is not used by cells as energy.
