Which of the following hill ranges marks the northern boundary of the Chota Nagpur Plateau?

💡 Solution & Explanation

The Kaimur Range represents the easternmost continuation of the Vindhyan mountain system and forms the distinct northern boundary of the Chota Nagpur Plateau. Other formations like the Satpura Range or Rajmahal Hills occupy different geographical zones relative to the plateau. This escarpment acts as a major watershed separating the Son river valley from the Gangetic plains. A related geographical feature is the presence of ancient sedimentary rock formations rich in limestone across the Kaimur region.
