The correct answer is: a) Shivalik Hills and neighboring areas.
The Shivalik Hills are a mountain range in the northern Indian state of Punjab. They are part of the Himalayas and are a continuation of the foothills of the Himalayas. The Shivalik Hills are made up of sedimentary rocks and are relatively young, geologically speaking. This makes them more susceptible to earthquakes than other parts of Punjab.
The Central Plains of Punjab are located in the center of the state. They are a flat, fertile region that is home to most of Punjab’s population. The Central Plains are not as susceptible to earthquakes as the Shivalik Hills, but they are still at risk.
The Southwest border region of Punjab is located along the border with Pakistan. This region is also at risk of earthquakes, as it is located near the Himalayas.
The Wetlands of Punjab are located in the southeastern part of the state. They are a relatively safe region from earthquakes, as they are not located near any major fault lines.
In conclusion, the Shivalik Hills and neighboring areas are the most vulnerable to earthquakes in Punjab. This is because they are made up of sedimentary rocks and are relatively young, geologically speaking.
