Answer:

Option (C)

Step-by-step explanation:

Volcanoes are formed along a convergent plate boundary. When volcanic eruptions takes place, it emits pyroclastic materials along with various types of harmful gases that are accumulated in the atmosphere. As a result of this, the atmosphere gets block and it does not allow the sunlight to reach on the earth's surface. Due to this, a huge amount of plant species gets extinct as it becomes impossible for the plants to carry out the photosynthesis process.

Thus, this entire process takes place by interacting with the 3 spheres, namely the biosphere, atmosphere and geosphere.

Hence, the correct answer is option (C).
