Bijapur’s renowned acoustic feature known as the ‘Whispering Gallery’ is found in which monument?

The correct option is Gol Gumbaz.

Step-by-Step Explanation:

1. Overview of Gol Gumbaz:
Gol Gumbaz, located in Bijapur (officially known as Vijayapura) in Karnataka, India, is the mausoleum of King Mohammed Adil Shah, the seventh ruler of the Adil Shahi dynasty. Constructed during the 17th century, it features one of the largest single-chamber structures and domes in the world.

2. The Acoustic Phenomenon of the 'Whispering Gallery':
Inside the monumental dome of Gol Gumbaz lies a circular gallery running along its inner perimeter. This area is famously referred to as the Whispering Gallery.
- Due to the unique acoustic design and concave curvature of the dome's walls, sound waves undergo multiple consecutive reflections.
- As a result, even the faintest whisper or softest sound made at one end of the gallery can be heard with surprising clarity directly on the opposite side, approximately 37 meters (120 feet) away.
- Furthermore, a single sharp sound or clap produced in the gallery reverberates and echoes 7 to 11 times.

3. Analysis of Other Options:
- Chand Minar: A historic tower located in Daulatabad, Maharashtra, erected as a victory monument.
- Ibrahim Rauza: Another famous monument in Bijapur (the tomb complex of Ibrahim Adil Shah II), often called the "Taj Mahal of the Deccan" for its exquisite stone carvings, but it does not feature the famous whispering gallery.
- Jama Masjid: A prominent congregational mosque in Bijapur built by Sultan Ali Adil Shah I.

Hence, Bijapur’s renowned acoustic 'Whispering Gallery' is housed in Gol Gumbaz.
