Final answer:
Krishna is an avatar of Vishnu, which is true, and fulfills various roles within Hindu mythology, including guiding Arjuna in the Bhagavad Gita. Hinduism has no single founder and evolved from various Indian cultures and traditions.
Step-by-step explanation:
Krishna is indeed one of the avatars (incarnations) of the god Vishnu, making statement A 'True'. In Hinduism, Vishnu is known as the Preserver and is one of the three principal deities, alongside Brahma the Creator and Shiva the Destroyer. Vishnu's avatars, including Krishna, descend to earth to bring order and righteousness, often at times of great turmoil or evil. In the epic Mahabharata, Krishna plays a critical role by advising the warrior Arjuna on the battlefield, revealing profound spiritual and philosophical concepts. This dialogue is captured in the revered scripture, the Bhagavad Gita. Krishna's various depictions reflect his diverse roles – from a divine child and prankster to a charismatic lover and a wise guide.
As for the founder of Hinduism, it does not have a single founder like some other religions. Instead, it evolved over centuries with contributions from many individuals and encompasses a wide range of beliefs and practices. Therefore, neither A Krishna nor B Buddha can be called the 'founder' of Hinduism, as it is a synthesis of various Indian cultures and traditions.
