According to seismic activity maps and earthquake data, (d) Orissa is the region where major earthquakes are less likely to occur compared to the other options.
Explanation: While earthquakes can happen anywhere, Orissa is generally considered to be less seismically active compared to regions like North East India, Rann of Kutch, and Rajasthan.
Key points about the other options:
North East India:
This region is known for its high seismic activity due to the proximity of tectonic plate boundaries, leading to a higher risk of major earthquakes.
Rann of Kutch:
This area in Gujarat is situated on a major fault line and is considered highly prone to earthquakes.
Rajasthan:
Although not as earthquake-prone as some other regions, Rajasthan can still experience tremors.
