Ans. Option B is correct.

Statement 1 is correct  After the upliftment of Himalayas, northern movement of Indian Plate also created a trough to the south of Himalayas. The raising of Himalayas and subsequent formation of glaciers gave rise to many new rivers which supplied more alluvium to intensify the filling of the trough.

Statement 2 is correct  Gradually, the depression got completely filled with alluvium, gravel, rock debris (conglomerates) and the Tethys Sea completely disappeared leaving behind a monotonous aggradational plain

Statement 3 is not correct  It stretches for about 3,200 km from the mouth of the Indus to the mouth of the Ganga. Indian sector of the plain accounts for 2,400 km. The northern boundary is well marked by the Shiwaliks and the southern boundary is a wavy irregular line along the northern edge of the Peninsular India.
