Correct option is A. Kabir
Kabir emphasised the essential oneness of all religions by describing Hindus and Muslims ‘as pots of the same clay’. To him Rama and Allah, temple and mosque were the same. He regarded devotion to god as an effective means of salvation and urged that to achieve this one must have a pure heart, free from cruelty, dishonesty, hypocrisy and insincerity. He is regarded as the greatest of the mystic saints and his followers are called Kabir panthis.
