Question

Who was the patron of the 3rd Buddhist council ?
A. Ajatashatru
B. Ashoka
C. Kanishka
D. Harsha

Answer 1

Hint:
The customary explanation behind assembling the Third Buddhist Council is accounted for to have been to freed the Sangha of debasement as adversaries who in the pretense of allies had penetrated the Sangha, just as priests who held blasphemous perspectives. The committee prescribed the ruler Ashoka to oust 60,000 brahmanic spies just as reexamining the Pāli Canon.

Complete answer:
The Third Buddhist committee was assembled in around 250 BCE at Asokarama in Pataliputra, apparently under the support of Emperor Ashoka. This is anyway contested, as notice of the chamber never shows up in the Edicts of Ashoka.
The record of the foundation to the Third Council is as per the following: Emperor Ashoka was delegated in the 200 and eighteenth year after the Buddha's parinibbāna. From the start, he paid just symbolic reverence to the Dhamma and the Sangha and furthermore upheld individuals from other strict orders as his dad had done before him. Nonetheless, this changed when he met the devout amateur priest Nigrodha who lectured him Appamada-vagga refrains from the Dhammapada. From that point, he stopped supporting other strict gatherings and his advantage in and dedication to the Dhamma developed. He utilized his tremendous abundance to construct, it is stated, 84 thousand pagodas and viharas and to sumptuously uphold the bhikkhus (priests) with the four necessities. His child Mahinda and his little girl Sanghamitta were appointed and admitted to the Sangha.

Hence, the correct answer is option B.

Note:
The Dhamma missions to Sri Lanka and Kashmir and Gandhara were exceptionally effective, prompting a drawn-out presence and strength of Buddhism in those regions.
It isn't clear precisely how compelling the connections to Egypt and Greece may have been, however a few creators have remarked that some degree of syncretism between Hellenist thought and Buddhism may have begun in Hellenic terrains around then. They have highlighted the presence of Buddhist people group in the Hellenistic world around that period, specifically in Alexandria (referenced by Clement of Alexandria), and to the pre-Christian religious request of the Therapeutae (conceivably a distortion of the Pali word "Theravada"), who may have "predominantly drawn (its) motivation from the educating and practices of Buddhist austerity" (Robert Linssen).
