The correct answer is: a) Earthquakes.
Punjab is a state in northwestern India. It is located in the Indo-Gangetic Plain, which is a seismically active region. The state has experienced several earthquakes in the past, including the 1905 Kangra earthquake, which killed over 20,000 people.
Cyclones are tropical storms that form over warm waters in the Indian Ocean. They can cause heavy rains, flooding, and high winds. Punjab is not located in a cyclone-prone area.
Tsunamis are large waves that are caused by earthquakes or volcanic eruptions. They can cause widespread damage and loss of life. Punjab is not located in a tsunami-prone area.
Volcanic eruptions are caused by the release of magma from the Earth’s mantle. They can cause ashfalls, lava flows, and pyroclastic flows. Punjab is not located in a volcanically active area.
In conclusion, Punjab is moderately prone to earthquakes. The state has experienced several earthquakes in the past, and it is located in a seismically active region.
