D. Chishti Sufis belonged to three different branches of the Chishti order – Nagauriya, Sabiriya and Nizamiya.
Choose the correct answer :

The correct answer is (C) A, B and D

Explanation:
• The Firdausi order was indeed a branch of the Suhrawardi silsila and was very popular in Bihar.
• The Shattari order was known for its orthodox approach and synthesis of Sufi thoughts with Vedantic ideas, popular in Gwalior and Bengal.
• The Chishti order branched into several sub-lineages, notably the Nagauriya (after Hamiduddin Nagauri), Sabiriya (after Alauddin Sabir Kaliyari), and Nizamiya (after Nizamuddin Auliya).
• Statement C is incorrect because the major orders that flourished in the Deccan were the Chishti and the Naqshbandi, not a "Qureshi" order as a primary regional branch.

Information Booster:
• Moinuddin Chishti founded the Chishti order in India.
• Sheikh Shihabuddin Suhrawardi founded the Suhrawardi order.
• Bahauddin Zakariya was the most influential Suhrawardi saint in Multan.

Additional Knowledge:
• Qureshi is a common lineage name but not recognized as a major flourishing independent Sufi silsila in the Deccan in the context of standard Sufi history.

So the correct answer is (c)
