A. geosphere, atmosphere, and biosphere B. hydrosphere, geosphere, and biosphere C. atmosphere, geosphere, and cryosphere D. biosphere, cryosphere, and hydrosphere

The hydrosphere is the system composed of all the water of the earth, mainly in liquid and solid-state. The biosphere is the terrestrial system composed of living beings its relationship with planet earth. The geosphere is the system that composes the earth and is divided into 3 layers, nucleus, mantle and bark; in it, the origin of terrestrial phenomena such as earthquakes, volcanism, and mountain formation occurs.

According to the above, when we take as reference the initial sentence "a volcanic eruption takes place under the ocean, Huge waves crash against the shores and destroy houses of people." A volcanic eruption occurs in the geosphere; the huge swell forms in the hydrosphere; Finally, the destruction of people's homes has to do with the biosphere. Then, the correct answer is B. Hydrosphere, geosphere and biosphere.

B. The Geosphere is also known as the Lithosphere which is disturbed during this process along with the hydrosphere which pertains to the oceans.
