Correct option is D
William King is considered the father of Indian prehistory due to his significant contributions to the study of ancient human remains and prehistoric archaeology in India. He is best known for his identification of the Homo heidelbergensis species and his work in the study of prehistoric cultures in India. King’s research laid the foundation for future archaeological explorations, and his findings provided early evidence of human habitation in India during the Paleolithic period. Although Sir John Marshall and Alexander Cunningham made major contributions to Indian archaeology, King’s work in prehistory, particularly in the Indian subcontinent, earned him this title.
