Which of the following is NOT one of the five major world religions?

Confucianism is often classified as a philosophical system or ethical framework rather than a religion in the same sense as the other options listed. The five major world religions typically include Hinduism, Buddhism, Islam, and Christianity. While Confucianism has significant cultural and social influence, particularly in East Asia, it does not encompass the same elements of worship and belief in the divine that characterize the major world religions. The other choices—Hinduism, Islam, and Buddhism—are recognized as religions with established doctrines, practices, and large followings.
