The correct option "Neither 1 nor 2" is accurate because the 'Bijak' is actually a collection of the verses and teachings of Saint Kabir, not Dadu Dayal. Additionally, the Philosophy of Pushti Marg was propounded by Vallabhacharya, not Madhvacharya, who is associated with the Dvaita philosophy. These distinctions are important in understanding Indian religious traditions and their key figures, which are often tested in UPSC exams for their impact on culture and social reform movements.
