The Iqta system was not an ancient indigenous institution of India. It was an administrative and land distribution system of Persian origin, introduced by the early Delhi Sultans, particularly Iltutmish. Under this system, land assignments (Iqtas) were granted to military officers (Iqtadars) in exchange for their services, including maintaining troops and collecting revenue. The Iqta was generally non-hereditary and transferable.
Statement 3 is incorrect.
The office of Mir Bakshi was a creation of the Mughal administration, not the Khalji Sultans of Delhi. Emperor Akbar established this position as the head of the military department. The Mir Bakshi was responsible for military organisation, recruitment, payment of salaries to Mansabdars, and the overall management of the imperial army. In the Delhi Sultanate, the corresponding head of the military department was known as the Ariz-i-Mumalik.
