(B) Metamorphic rocks
(C) Shale
(D) Sedimentary rocks

Answer 1

Hint: The Peninsular level is a tableland made out of the old translucent, volcanic and transformative rocks. It was shaped because of the breaking and floating of the Gondwana land and subsequently, making it a piece of the most seasoned landmass.

Complete Answer:
Toward the south of the Yamuna stream between the Madhya Bharat Pathar and the Vindhyan Scarplands is the old analyzed upland of the 'Bundelkhand gneiss' compris¬ing of rock and gneiss. This is called Bundelkhand upland. Covering a zone of around 54,560 sq km this upland spread more than five locale of Uttar Pradesh (Jalaun, Jhansi, Lalitpur, Hamirpur, and Banda) and four areas of Madhya Pradesh (Datia, Tikamgarh, Chhatarpur, and Panna).

With a normal height of 300-600 m above ocean level, this zone inclines down from the Vindhyan Scarp toward the Yamuna River. The territory is perceived by a mass of adjusted hummocky slopes made of stone and sandstone. In the north-west and north-east, the framework is covered by the Ganga-Yamuna alluvium and in the south-west by the Deccan Trap.

The erosional work of the waterways streaming here has changed over it into an undulating territory and delivered it ill-suited for development. The locale is described by decrepit geology. About 67.7 percent of the zone is under 300 m and just 3.6 per cent is over 450 m in elevation. Streams like Betwa, Dhawan, and Ken have cut out steep canyons, abrupt rough banks, and cascades.

Hence the correct answer is the option (A).

Note: The level has expansive and shallow valleys and adjusted slopes. This level comprises two wide divisions, in particular, the Central Highlands and the Deccan Plateau. The piece of the Peninsular level misleading the north of the Narmada waterway covering a significant territory of the Malwa level is known as the Central Highlands.
