Indian Economy - Understanding the basics of Indian economic system

Consider the following statements:

1.Peneplain is a lowland offaint relief with some low resistant remnants called monadnocks formed due to running water erosion.

2.Pediplain found at the foot of glacial mountains are covered with glacio-fluvial deposits.

3.Outwash plain is an erosional plain formed due to torrential rain in arid regions.

How many of the statements given above are incorrect?

Only One

Only Two

All Three

None

Peneplain is a lowland of faint relief with some low resistant remnants called monadnocks formed due to running water erosion: This statement is correct. A peneplain is a nearly level surface of low relief that is underlain by nearly horizontal strata. Monadnocks are resistant rock outcrops that stand above the general level of the peneplain.
Pediplain found at the foot of glacial mountains are covered with glacio-fluvial deposits: This statement is incorrect. Pediplains are low-relief erosional surfaces, but they are typically associated with arid regions rather than glacial mountains. Glacio-fluvial deposits are more commonly found in areas influenced by glacial processes, not in pediplains.
Outwash plain is an erosional plain formed due to torrential rain in arid regions: This statement is incorrect. Outwash plains are typically associated with glacial environments, not arid regions. They are formed by the deposition of sediment carried by meltwater streams from a glacier.
