Which of the following pairs is NOT correctly matched?

The correct answer is A. Adina Masjid is at Pandua in Malda district of West Bengal, not at Mandu. It was built by the Ilyas Shahi ruler Sikandar Shah in the 1360s-70s and was among the largest mosques in the subcontinent in its time. Mandu, in Malwa, has its own monuments, such as the Jami Masjid, Dilawar Khan's Mosque and the Hoshang Shah tomb.

• B is correctly matched. The Lal Darwaza Masjid at Jaunpur belongs to the Sharqi period of the Jaunpur Sultanate.
• C is correctly matched. The Dakhil Darwaza is the monumental gateway at Gaur, the Bengal Sultanate capital.
• D is correctly matched. The Teen Darwaza is the triple-arched gateway at Ahmedabad, built under the Gujarat Sultanate.

The core concept is Sultanate architecture: the Delhi, Bengal, Jaunpur, Malwa and Gujarat styles, and how regional capitals developed distinct idioms. For Mains, this links to art and culture questions on regional architectural traditions.

Trap: aspirants pick A because they associate Mandu with Malwa's Afghan-era monuments and forget that Adina belongs to Bengal.
