Which of the following religious figures is recognized as the founder of the Baha'i faith?

Baha'u'llah is recognized as the founder of the Baha'i faith, which emerged in the 19th century. His teachings and writings laid the foundation for the Baha'i religion, emphasizing the oneness of humanity, the unity of religions, and the importance of world peace. Baha'u'llah claimed to be the fulfillment of the prophecies of multiple religions and unified various religious truths, promoting the belief that all major religions come from the same divine source.

While The Bab was a significant figure in the early history of the Baha'i faith and is credited with preparing the way for Baha'u'llah, he did not found the religion himself. Guru Nanak is the founder of Sikhism, and Prophet Muhammad is recognized as the founder of Islam, making their relevance to the Baha'i faith distinct from the role of Baha'u'llah.
