Answer:
Option (C)
Explanation:
Tsunamis are defined as the series of waves that are produced in a large water body such as oceans and seas, due to the occurrence of an earthquake, underwater explosion as well as due to the eruption of a volcano.
The tsunami warning system is an instrument that is commonly used in order to detect the occurrence of a tsunami in advance and also to issue the warnings so that the loss of property and life can be reduced.
There is no tsunami warning system in the Indian ocean, as a result of which the people living in the near coastal areas were not warned. This is why the citizens were not prepared and thereby caused a lot of damages to the properties.
Thus, the correct answer is option (C).
