Answer:
C). Creon's decree.
Explanation:
As per the question, the biggest obstacle that Antigone must conquer to attain her goal is 'King Creon's decree'. Creon's proclamation declared that Plyneices' body shall not receive appropriate cremation and will be left in open to rot in contrary to high honorary burial for Eteocles.
