Understanding the Hill Range Connection
The question requires identifying the north-south hill chain that connects the predominantly east-west running Garo, Khasi, Jaintia, and Naga Hills.
Geographic Context of Eastern Hills
The Garo, Khasi, Jaintia Hills are situated in Meghalaya, while the Naga Hills are located further east. These ranges form part of the northeastern Indian peninsular geology.
Identifying the Connecting North-South Chain
We need to evaluate which option presents a hill system oriented north-south and geographically positioned to link these eastern ranges.
- Option 1 includes Nilgiri Hills (South India), which is geographically distant.
- Option 2 correctly identifies the Mizo Hills (northeast India, running north-south) and the Rakhine Hills (Myanmar, continuing the north-south trend). This chain geographically connects the Garo, Khasi, Jaintia, and Naga Hills southward.
- Option 3 includes Satpura Hills (central India, east-west), which does not form this connection.
- Option 4 includes Vindhya Hills (central India, east-west), which is also geographically irrelevant to this specific connection.
Finalizing the Connection
The Mizo Hills and Rakhine Hills provide the necessary north-south alignment connecting the specified eastern hill ranges.
