Complete answer:
Cyclones: Cyclones are like storms which take place on large bodies of water. It is due to rotating or spinning of wind. These are basically large systems of air mass that are rotating. These occur at areas with lower atmospheric pressure.
Thunderstorm: Thunderstorms are the storms with lightning and thunder. These are formed due to moisture from humid air. It can have precipitation, lightning and heavy winds. It develops frequently in hot and humid tropical areas.
Tornado: Tornadoes are rotating columns of air which are accompanied by dark funnel shaped clouds that progress over the land. It generally develops over land and sea. It is accompanied by hail, lightning and heavy rain.
Earthquake: When there is a sudden release of energy in the Earth's surface, seismic waves are produced which leads to shaking of the surface of the Earth. This shaking if earth is called Earthquake.

Option D is the correct answer.

Note: Thunderstorms and cyclones are nearly the same due to their cause of occurrence. The difference between them is that the cyclones are spinning but the thunderstorm may not always rotate in nature. Tornadoes are primarily an over-land phenomenon. Tornadoes are more devastating as compared to thunderstorms. Factors like temperature, humidity and wind speed contribute to the occurrence of the cyclone.
