The correct answer is (b), Jahangirnama.
The Jahangirnama is a 17th-century memoir written by the Mughal emperor Jahangir. It is a valuable source for the history of the Mughal Empire, but it is not a source for the history of Uttarakhand. Uttarakhand is a state in northern India that was not part of the Mughal Empire.
The other three options are all sources for the history of Uttarakhand. Tarikh-i-Badauni is a 16th-century history of the Mughal Empire written by the historian Abdul Qadir Badauni. Shahjahannama is a 17th-century history of the Mughal Empire written by the historian Abdul Hamid Lahori. Babarnama is a 16th-century memoir written by the Mughal emperor Babur. It is a valuable source for the history of the Mughal Empire and for the history of Uttarakhand, as Babur conquered and ruled parts of what is now Uttarakhand.
