Solution:Sautrantika and Sammitiya were the sects of Buddhism, not Jainism. So, statement 1 is incorrect. Sarvastivada literally means "Doctrine that all exist". Sarvastivadin described a complex system in which past present and future phenomena are all held to have some form of their own existence.Like all Buddhist, the Sarvastivadins consider everything empirical to be impermanent but they maintain that the dharma factors are eternally existing realities. Impermanence, also called Anitya, is one of essential doctrines and part of three marks of existence in Buddhism.
This doctrine was presented by Buddha himself. The doctrine asserts that all of conditioned existence, without exception, is "transient, evanescent, inconstant". This impermanence is a source of Dukkha (suffering).
