With reference to Indian history, who of the following were known as “Kulah-Daran”?

The correct option is Sayyids.

In the context of medieval Indian history, especially during the Delhi Sultanate period, the Sayyids were known as “Kulah-Daran” (pointed cap-wearers).
The term is derived from two Persian words: Kulah, which means a high pointed cap, and Daran, which refers to those who wear or possess it.

The Sayyids claimed direct descent from the Prophet Muhammad through his daughter Fatima. Due to their distinguished lineage, they held a highly respected and elite position in Muslim society.
During religious, official, and ceremonial occasions, they wore a distinctive high, pointed cap (known as the kulah) as a mark of their special status, identity, and prestige, which led to them being referred to as "Kulah-Daran".
