The correct answer is: Only I.
Vallabhacharya was a 16th-century Indian philosopher and theologian who founded the Pushtimarga sect of Vaishnavism. His doctrine emphasized the importance of devotion to Krishna, and his followers are known for their elaborate rituals and festivals. The International Society for Krishna Consciousness (ISKCON), commonly known as the Hare Krishnas, was founded in 1966 by A.C. Bhaktivedanta Swami Prabhupada, a disciple of Vallabhacharya. However, ISKCON is not a direct descendant of Vallabhacharya’s sect, and Vallabhacharya himself is not considered to be the founder of ISKCON.
Option I is correct because Vallabhacharya’s doctrine came to be known as “Pushti Marga” for his successors laid stress on the physical side of Krishna’s sports. This is evident in the Pushtimarga tradition’s emphasis on the use of rasalila, or dance, as a form of devotion.
Option II is incorrect because Vallabhacharya is not the founder of the International Society for Krishna Consciousness.
