The correct option is "Neither 1 nor 2" because Bijak is actually the compilation of the teachings of Saint Kabir, not Dadu Dayal. Similarly, the Philosophy of Pushti Marg, which emphasizes devotion to Lord Krishna, was established by Vallabhacharya, not Madhvacharya, who is associated with the Dvaita school of Vedanta. This distinction is crucial for UPSC Prelims as it tests the understanding of key figures and their contributions in Indian philosophical and spiritual traditions. Familiarity with these details is essential for accurately answering questions based on Indian history and culture.
