Answer 1

All of the above

Explanation:

• Young fold mountains like the Himalayas and Alps are still forming and have sharp peaks due to ongoing tectonic activity.
• Old fold mountains, such as the Urals and Aravallis, have been eroded over time, resulting in gentler slopes and rounded tops.
• Residual mountains like the Nilgiri and Rajmahal Hills are remnants of older mountains that have been extensively weathered and eroded, leaving behind smaller, rounded landforms.
