The statement "Elphinstone wrote that Humayun- nama is only real historical text among texts of Asia" is false. While Mountstuart Elphinstone was an important historian and administrator who wrote about India, this specific quote attributed to him regarding the 'Humayun-nama' is not accurate or widely recognized. The 'Humayun-nama' itself is considered a valuable historical text, but the extreme claim attributed to Elphinstone is incorrect. The other statements are generally true about the 'Humayun-nama'.
