Answer:
B. Sri Lanka, Southeast Asia, and eastern Asia
Step-by-step explanation:
Buddhism is a religious, philosophical and spiritual doctrine and its precept is the reincarnation of the human being in order to bind us to the sufferings of the material world. Buddhism represents an attitude towards the world, a behavioral technique. His followers learn to detach themselves from all that is transitory, which results in a kind of spiritual self-sufficiency.
Buddhism is very influential in Asia. After Buddha's death, Buddhism spread significantly between Sri Lanka, Southeast Asia, and East Asia.
