Correct Answer - Option 1 : Someshwar Hilly Range

The correct answer is Someshwar Hilly Range.

  • Someshwar Hilly Range landforms occupy the North-Western parts of Bihar State.
  • Someshwar Hilly Range:
    • This Regin consists of a different range of hills and valleys, all parallels to the Nepal border in the NW to SE direction.
    • The average width of this range is 4-6 km.
    • The avg. height of his range is about 450 meters.
    • The highest peak is the Someshwar fort (865 meters).
    • There are some natural passes formed by the river.
    • This range consists of relatively young sedimentary rocks of which sandstone and pebbles are important.

  • Kaimur Plateau:
    • Kaimur Hills, also called Kaimur Range, the eastern portion of the Vindhya Range, starting near Katangi in the Jabalpur district of Madhya Pradesh and running generally east for a distance of about 300 miles (480 km) to Sasaram in Bihar.
    • Its maximum width is about 50 miles (80 km).
    • After traversing the northern part of Jabalpur and southeast Maihar, the range turns to the east and runs through Rewa.
    • There it separates the valley of the Son and Tons rivers and continues into the Mirzapur district of Uttar Pradesh and the Shahabad district of West Bengal.
    • The range has a distinctive jagged appearance in Madhya Pradesh, with metamorphic rock formations and upheaved rock strata.
    • The range almost disappears at places, being marked by a low chain of rocks, and it never rises more than a few thousand feet above the plain.
    • The ruined fort of Rohtas is situated in these hills, and archaeological explorations have uncovered well-preserved prehistoric rock art and paintings in caves and sheltered areas in Bihar.
  • Nawada Hilly Region:
    • Nawada Hilly Region is situated in the Magadh division in South Bihar. 
    • It has an average elevation of 80 meters (260 ft) above sea level with an area of 2,492 km2 (962 sq mi).
    • It is bounded in the North by Nalanda District, in the East by Sheikhpura & Jamui District, in the west by Gaya district and the southern border of the district shared by Koderma & Giridih districts of Jharkhand state.
  • Rajgir Hilly Region:
    • Rajgir Hills, small isolated upland region of central Bihar state, northeastern India.
    • The hills are known for their scenic beauty and as a historical and religious center for Hindus, Buddhists, and Jains.
    • The formation, composed of massive quartzites, rises sharply from the South Bihar Plains.
    • The hills extend northeast-southwest for some 40 miles (65 km) in two roughly parallel ridges that enclose a narrow ravine in the northeast that opens gradually toward the southwest.
    • Their summits resemble forested islands in the flat, largely featureless surrounding alluvial lowland.
    • At one point the hills rise to an elevation of 1,272 feet (388 meters) above sea level, but, in general, they seldom exceed 1,000 feet (300 meters).
