Which of the following is not true about the Ain-i Akbari?

The correct option is: Undertaken at the order of Emperor Akbar and completed at the time of Shah Jahan

Explanation:
The Ain-i Akbari (meaning the "Administration of Akbar") is a detailed 16th-century document detailing the administration of the Mughal Empire under Emperor Akbar, written by his court historian, Abu'l-Fazl.

Let us evaluate the statements to understand why the selected option is not true:

1. It was completed in 1598: This is a true statement. The document went through five revisions and was finally completed in the year 1598 during the reign of Akbar.

2. This is a view of the regions from the centre: This is also a true statement. The book presents the empire from the perspective of the imperial center, organizing data and descriptions around Akbar's court and central authority.

3. It provides quantitative information of various provinces: This is true. The Ain-i Akbari is famous for its rich statistical information, detailing administrative divisions, crops, yields, prices, revenue collections, and military strength of different provinces.

4. Undertaken at the order of Emperor Akbar and completed at the time of Shah Jahan: This statement is incorrect. While it was indeed commissioned by Akbar, it was also completed during Akbar's lifetime and reign (in 1598). Shah Jahan was Akbar's grandson and ruled much later, from 1628 to 1658. Therefore, it was not completed during Shah Jahan's reign.
