With reference to Indian history, who of the following were known as "Kulah-Daran"?
Explanation
The Sayyids were known as "Kulah-Daran" (cap-wearers) because they wore a distinctive pointed cap (*kulah*) to signify their high social and religious status as descendants of the Prophet Muhammad during the Delhi Sultanate. While Qalandars were wandering Sufi dervishes who also had unique appearances, the specific term "Kulah-Daran" is historically reserved for the elite Sayyid class. This question tests the core concept of social stratification and terminology associated with the religious and administrative classes in medieval India.
