Areawise, which one of the following is the largest Lok Sabha constituency ?

Ladakh is the largest Lok Sabha constituency in India in terms of geographical area. Spanning approximately 173,266 square kilometers, it covers the entire Union Territory of Ladakh, including the districts of Leh and Kargil [t1][t2]. This vast expanse makes it significantly larger than other major constituencies like Kutch in Gujarat, which is the second largest by area [t4]. While the Constitution mandates that constituencies should have roughly equal populations to ensure equal vote value, geographical factors in sparsely populated regions like the Himalayas result in massive territorial sizes for single seats [c1][c4]. In contrast, the smallest constituency by area is Chandni Chowk in Delhi, while the largest by number of electors is Malkajgiri in Telangana [t2]. Ladakh has been a single-member constituency since 1967 and remains the most expansive parliamentary seat in the country [t1].
