Concept:
• The Chishti Silsila (order) was one of the most influential Sufi orders in the Indian subcontinent.
• Sufi saints established 'Khanqahs' (hospices), and after their death, their tombs became 'Dargahs' which served as major centers of pilgrimage (Ziyarat).
• Each major Chishti saint is associated with a specific city where their shrine is located.
Step 1: Validate the pairs for A, C, and D
Shaikh Fariduddin (Baba Farid) is buried in Ajodhan (modern Pakpattan, Pakistan). Shaikh Nasiruddin, known as 'Chirag-i-Delhi', has his Dargah in South Delhi. Khwaja Qutbuddin Bakhtiyar Kaki, the disciple of Moinuddin Chishti, also has his Dargah in Mehrauli, Delhi. These three pairs are correct.
Step 2: Identify the error in pair B
Shaikh Nizamuddin Auliya, one of the most famous Sufi saints of the Chishti order, spent most of his life in Delhi. His Dargah is a world-famous pilgrimage site located in the Nizamuddin West area of Delhi, not Agra.
Step 3: Conclusion
Since pair (B) incorrectly attributes the location of the Dargah to Agra, it is the "odd one out" in the given list.
