The correct answer is: D. Chamba
Hiranand Sastri was a 19th-century Indian historian and scholar who wrote extensively on the history and culture of the Indian subcontinent. He is best known for his work on the Vamshavali (Genealogies) of the royal family of Chamba, which he compiled in the early 1880s. The Vamshavali is a valuable source of information on the history of Chamba, and it is considered to be one of the most important works of its kind.
