Question

Any sound made in the inner gallery of Gol Gumbaz gives rise to multiple echoes and returns it to the same person several times.

Answer 1

Hint: Gol Gumbaz is the catacomb of king Muhammad Adil Shah, Adil Shah Dynasty. Development of the burial place, situated in Vijayapura , Karnataka, India, was begun in 1626 and finished in 1656. The name depends on Gola gummata from Gol Gumbaz signifying "roundabout arch". It follows the style of Indo-Islamic engineering.

Complete Answer: Gol Gumbaz is situated in Bijapur. It was developed by Adil Shah II. It is otherwise called the murmuring display since when one murmurs, the waiting reverberation of a murmur is heard in the contrary corner.Gol Gumbaz design is novel. It stands gloriously, as a tribute to the balance and tastefulness of Islamic design, it bears the sign of the Islamic style of engineering in its general structure, the vault, the minarets, and semi-round entryways, and so forth Be that as it may, what truly makes this structure one of a kind are: The focal vault of the Gol Gumbaz has a measurement of 44 meters, making it the second-biggest arch on the planet after the arch of St. Diminish's Basilica in the Vatican . Another momentous component of the vault is that it stands gladly without the help of columns!
Within the tomb has a chamber which has a region of 1,700 Sq./meters, making it one of the greatest single chamber spaces on the planet Inside the catacomb is a roundabout exhibition, directly underneath the burial chamber, this is known as the murmuring display, the extraordinary structure is implicit such a way that a little murmur gets intensified and is conveyed over a separation of in excess of 40 meters in the huge arch and can be heard obviously. Another amazing component is that any stable made inside is repeated back 7 to multiple times!

So, the correct answer is option (A).

Note: The structure is made out of a solid shape, 47.5 m (156 ft) on each side, covered by a rooftop 44 m (144 ft) in outside measurement. Eight meeting curves made by two pivoted squares that make interlocking pendentives uphold the vault. At every one of the four corners of the solid shape, is a vault covered octagonal pinnacle seven stories high with a flight of stairs inside. The upper floor of each pinnacle opens on to a round exhibition which encompasses the arch. The arch is probably the biggest vault developed before the advanced period.
