Which one of the following monuments has a dome which is said to be one of the largest in the world ?

The Gol Gumbaz (Gol Gumbad) at Bijapur is the mausoleum of Mohammad Adil Shah and is famously named for its massive round dome; the monument and its dome are highlighted in standard architectural accounts of Deccan and Bijapur heritage [2]. Authoritative educational and government sources note the dome’s exceptional scale: NCERT describes Gol Gumbaz as having the largest dome built in India, and the Vijayapura (Bijapur) district website states the vast dome is regarded as the second-largest unsupported dome in the world after St. Peter’s Basilica [4]. These consistent references identify Gol Gumbaz (option 4) as the monument with one of the world’s largest domes.
