(1) Re-acquisition of Iqtas – Correct.Balban reasserted central authority by taking back Iqtas (land assignments) that had become hereditary. He wanted to curb the power of nobles and bring discipline in the administrative system.
(2) Relation with the Afrasiyab dynasty – Correct.Balban is known to have maintained contact with the rulers of Central Asia, including the Afrasiyab dynasty, partly to legitimize his rule and establish international prestige.
(3) Court splendour – Correct - Balban emphasized royal dignity and maintained a grand court with Persianized pomp. He introduced practices like Sijda (prostration) and Paibos (kissing the feet) to emphasize the superiority of the monarch.
(4) Consolidation of Chalisa – Not Correct - This is the incorrect statement. Balban did not consolidate the Chalisa (group of 40 nobles) — rather, he weakened and suppressed it. The Chalisa was created by Iltutmish, but it became too powerful and challenged the Sultan's authority. Balban saw it as a threat and dismantled its power to establish strong central authority.
