The correct option is A Samprati
Samprati is regarded for his patronage and efforts to spread Jainism in east India. While in one source, he is described as nominally a Jain from birth (Sthaviravali 9.53), most accounts emphasize his conversion at the hands of the Jain monk Suhastisuri, the eighth leader of the congregation established by lord Mahavira Swami. After his conversion he was credited with actively spreading Jainism to many parts of India and beyond, both by making it possible for monks to travel to barbarian lands, and by building and renovating thousands of temples and establishing millions of idols. He was a disciple of Suhastisuriji. Hence, Option A is correct.
