What Led to the Rapid Demise of the Safavid Empire

What led to the rapid demise of the Safavid Empire?

A) Like the Ottoman Empire, the lack of a principle of succession led Abbas the Great to eliminate all capable rivals, leaving no capable ruler following his death.
B) The Safavid defeat at the battle of Panipat at the hands of a Russian army stripped the empire of its military forces just as pressure from outside enemies increased.
C) The collapse of the Safavid economy in the 18th century diminished the revenues of the empire to the point that the central government could no longer function.
D) The successful conquest of the Ottoman Empire overextended the Safavid resources, so that the central government became increasingly inefficient.
