Answer:
The concept of karma is reaping what you sowed. Basically, get consequences for actions a person has done. Religions that practice/ believe in karma are: Hinduism, Christianity, and Buddism.
Step-by-step explanation:
Buddism and Hinduism both believe in reincarination ( the belief of being reborn. ) They think that your actions can decide what you´ll be reborn as. For example, if a person was doing something bad / wrong in their life, they could be reborn as an animal, while a person who was honest and righteous could be reborn as a human. Christianty, has a different take on karma, it believes you get what you deserve in the afterlife, basically if you are good then you will go to heaven , meanwhile ¨sinners ¨ (people who also do bad things ) will go to hell.
