1. A

   A-(3), B-(4), C-(1), D-(2)

   Option A matches Sultan Garhi with Iltutmish, Red Palace with Balban, Jamat Khana Masjid with Alauddin Khilji, and Dhai Din Ka Jhopra with Qutbuddin Aibak. This pairing correctly attributes each historical Delhi Sultanate architectural monument to its exact builder. Sultan Garhi was built by Iltutmish for his eldest son, while Balban constructed the Red Palace. Alauddin Khilji added the Jamat Khana Masjid, and Qutbuddin Aibak built the Dhai Din Ka Jhopra in Ajmer.

2. B

   A-(3), B-(4), C-(2), D-(1)

   Option B pairs Sultan Garhi with Iltutmish and Red Palace with Balban, but incorrectly swaps the builders for Jamat Khana Masjid and Dhai Din Ka Jhopra. It erroneously attributes Jamat Khana Masjid to Qutbuddin Aibak and Dhai Din Ka Jhopra to Alauddin Khilji. These mis attributions make the sequence factually inaccurate regarding Sultanate architecture.

3. C

   A-(4), B-(3), C-(1), D-(2)

   Option C wrongly pairs Sultan Garhi with Balban instead of Iltutmish, while correctly linking Red Palace to Balban. It further assigns Jamat Khana Masjid to Alauddin Khilji and Dhai Din Ka Jhopra to Qutbuddin Aibak. Because the initial pairing for Sultan Garhi is incorrect, this option fails.

4. D

   A-(4), B-(3), C-(2), D-(1)

   Option D pairs Sultan Garhi with Balban and Red Palace with Iltutmish, reversing the primary builders for both monuments. It then correctly connects Jamat Khana Masjid to Alauddin Khilji and Dhai Din Ka Jhopra to Qutbuddin Aibak. Since multiple foundational pairings are reversed, this option stands entirely incorrect.

Summary. Official key is (a) because it accurately matches every medieval building in List-I with its correct historical builder in List-II. Sultan Garhi was constructed by Iltutmish, the Red Palace by Balban, Jamat Khana Masjid by Alauddin Khilji, and Dhai Din Ka Jhopra by Qutbuddin Aibak. Other options mix up these architectural associations and fail to provide the correct code combination. Careful verification of Delhi Sultanate monuments ensures only option (a) satisfies all criteria.
