c. the declaration created a separation between church and state.
d. the declaration abolished the three estates.

Correct  D. The declaration abolished the three estates.

Explanation:

Under the old regime (or "Ancien Régime," to put it in French), was full of inequality.  Under the Ancien Régime, the aristocracy in France enjoyed much rank and privilege.  Being a member of the "Second Estate" (the nobility or aristocracy) meant being exempt from most taxes that supported the nation.  The 98% of the population that made up the "Third Estate" paid the costs of running a kingdom that supported the king and the aristocracy.  (Note: The "First Estate," or clergy, included high-ranking members that were essentially aristocrats, as well as low-ranking persons like parish priests who were more like commoners.)
