Which one of the following statements is NOT correct?

A) Ali Mardan Khan introduced the ijara system of revenue farming in Bengal
B) Maharaja Ranjit Singh set up modern foundries to manufacture cannons at Lahore
C) Sawai Jai Singh of Amber had Euclid’s ‘Elements of Geometry’ translated into Sanskrit
D) Sultan Tipu of Mysore gave money for the construction of the idol of Goddess Sharada in the Shringeri temple

Option (1) is NOT correct. The system of revenue‑farming in Bengal was introduced by Murshid Quli Khan (Murshid Ouli Khan), who reorganized finances and “introduced the system of revenue‑farming,” not Ali Mardan Khan [1]. The remaining statements are conventionally accepted: Maharaja Ranjit Singh established modern foundries at Lahore for cannon manufacture; Sawai Jai Singh of Amber patronized the translation of Euclid’s Elements into Sanskrit; and Tipu Sultan of Mysore funded the construction of the idol of Goddess Sharada at Sringeri — all reflected in standard summaries of these regional rulers’ activities.
