Which of the following was an integral part of the Indo-Islamic form of architecture?

Domes

The correct answer is Option 1- Domes

Domes were an integral part of the Indo-Islamic form of architecture.

The other options are not typically associated with Indo-Islamic architecture. Shutter windows are more commonly found in traditional Indian architecture, while tall and steep slopes and square roofs are more commonly found in European architecture.

Domes were introduced to India by the Mughals, who were influenced by Persian and Central Asian architecture. Domes were used in a variety of Indo-Islamic buildings, including mosques, tombs, and palaces. Some of the most famous examples of Indo-Islamic domes include the Taj Mahal, the Jama Masjid in Delhi, and the Gol Gumbaz in Bijapur.

Domes were not only aesthetically pleasing, but they also served a practical purpose. They helped to keep the interiors of buildings cool in the hot Indian climate. Domes also helped to improve the acoustics of buildings, making them ideal for mosques and other large gathering places.
