Detailed Solution

Concept- Just keep in mind the reasons and implications of each phrase. Natural catastrophes are unfavorable occurrences brought on by Earth's natural processes, and they may have a negative impact on organisms' ability to live.
Let's go through each of the terms included in the query.
Floods: As we all know, a flood is a natural calamity caused by an excessive water flow. The most frequent type of natural catastrophe, floods occur when an excessive water flow submerges lower ground that is usually dry. Floods are typically caused by heavy precipitation, quick snowmelt, cyclones, or tsunamis in coastal areas.
Drought: A situation where there is a scarcity of items necessary for human survival. It may be food, liquids, etc.
Crop failure is the primary cause of the food shortfall. Lack of adequate precipitation, whether rain or snow, harms crops, lowers groundwater levels, and results in a general water scarcity.
Earthquake: Earthquakes happen when seismic waves are suddenly released from the Earth's lithosphere, shattering the planet's surface planes.
Tsunami: A tsunami is a massive wave caused by an underwater volcanic explosion or earthquake. Normal tidal sea waves created by wind and storms are not tsunami waves. When a tsunami is close to the beach, it behaves like a swift tide that enters further inland than usual water waves.
We may draw the conclusion that if there is no rain, crops may fail and there may be a drought by carefully examining each of these concepts.
Hence, the correct option is 2.
