Arrange the following monuments in a chronological order and select the correct answer from the codes given below: I. Rabia Daurani’s Tomb, Aurangabad II. Shershah Suri’s Tomb, Sasaram III. Humayun’s Tomb, Delhi IV. Atala Mosque, Jaunpur

The correct order is IV, II, III, I, so option B. Fix each monument to its patron and completion date and the sequence follows.

• IV. Atala Masjid, Jaunpur: begun under Firuz Shah Tughlaq in 1376-77 and completed in 1408 under the Sharqi sultans. It is the oldest of the four.
• II. Sher Shah Suri's Tomb, Sasaram: built 1540-45 by Sher Shah after he displaced Humayun. It stands in a lake in an Indo-Afghan style.
• III. Humayun's Tomb, Delhi: commissioned by Haji Begum around 1565 and completed about 1572. It is the first large Mughal char-bagh tomb and a precursor to the Taj Mahal.
• I. Rabia-ul-Daurani's Tomb (Bibi ka Maqbara), Aurangabad: built 1651-61 by Azam Shah for his mother, Aurangzeb's wife. It is the latest of the four.

Option A puts the 17th century tomb first. Option C places the 16th century Sasaram tomb before the 17th century Aurangabad tomb's predecessor, and it misplaces the Jaunpur mosque. Option D puts Humayun's Tomb, which was completed in 1572, ahead of Sher Shah's tomb and the 14th century mosque. For Mains, the sequence traces Indo-Islamic architecture from the Sultanate through the Afghan and Mughal phases.

Trap: Candidates often think Humayun's tomb came first because Humayun is the more famous name, or they date the Atala Masjid by the Sharqi dynasty's rule and place it after the Mughal monuments.
