Explanation:

Question 1

Natural hazards are broadly classified into tectonic (related to Earth's crust movements, like earthquakes) and climatic (related to weather/climate, like floods, droughts). Options A, B, D list specific hazards, not broad types. So C is correct.

Earthquakes are caused by the movement of tectonic plates in the Earth's crust. Heavy rainfall (A) causes floods, atmospheric conditions (B) relate to weather, and volcanic eruptions (D) can be a result of crust movements but not the direct cause of all earthquakes. So C is correct.

The Pacific Ring of Fire is a region around the Pacific Ocean with high seismic (earthquake) and volcanic activity due to tectonic plate boundaries. A is incorrect (it's not just islands), B is wrong (not a storm), D is wrong (not drought - prone). So C (even with a typo in the option, the meaning is clear) is correct.

Answer:

C. Tectonic and climatic hazards
