Explanation
A peneplain is a broad, almost featureless low-relief plain produced by prolonged erosion that wears down mountains nearly to base level. Monotonous relief, occasional residual hills (monadnocks), and a landscape shaped by long-continued erosion all describe a peneplain. It is not a lava plateau, a fault-block mountain, or a fold mountain. Hence option C is correct.
