The correct option is D Parivrajakas
Parivrajakas were seekers of truth who did not live permanently in any one place. They left their homes and wandered from village to village and forest to forest.Hence they were called Parivrajakas(wanderers) or Bhikshus (mendicants or those who begged). Among these Parivrajakas, Vardhamana Mahavira, Gautama Buddha, Makhkhali Goshala and Ajita Keshkambalin became very famous.
