Which of the following palaces is also known as Chittar Palace?

Umaid Bhawan Palace in Jodhpur is also known as Chittar Palace because it was built on Chittar Hill using locally quarried Chittar sandstone. Its construction ran from 1929 to 1943, partly as a famine-relief employment project, and it is one of the world's largest private residences. Gajner Palace (Bikaner) was a royal hunting lodge, Rambagh Palace (Jaipur) was a Maharaja's residence, and Deeg Palace (Bharatpur) is famed for its water gardens, so none of these carries the Chittar name.
