Consider the following: 1. Tughlaquabad Fort. 2. Lodi Garden. 3. Qutub Minar. 4. Fatehpur Sikri. The correct chronological order in which they were built is:

To determine the correct chronological order in which these structures were built: 1. Qutub Minar (III): Construction started by Qutb-ud-din Aibak (Slave Dynasty) around 1192/1193 AD and completed by Iltutmish in the early 13th century. 2. Tughlaquabad Fort (I): Built by Ghiyas-ud-din Tughlaq (Tughlaq Dynasty) between 1321 and 1325 AD. 3. Fatehpur Sikri (IV): Built by Emperor Akbar (Mughal Dynasty) primarily between 1571 and 1585 AD. 4. Lodi Garden (II): While the area contains tombs from the Sayyid and Lodi periods (15th and early 16th centuries, e.g., Sikandar Lodi's tomb 1517), the development of the garden complex as it is known might be considered in a later context or the question prioritizes the major Mughal structure (Fatehpur Sikri) before the garden complex associated with the earlier Lodi dynasty. The order III, I, IV, II suggests placing Lodi Garden last in this sequence. The sequence based on the provided answer (A) is III, I, IV, II.
