Answer:

C. Utilization of fossil fuels by humans for industrialization.

Explanation:

Frequent eruptions of large volcanoes were happening long before humans and will happen after humans too. They are not the reason why we are seeing so much CO2 in the last 200 years.

There are some naturally occurring fluctuations of carbon but not to the degree that we are seeing.

Melting of ice and sea levels rising is due to the global warming problem caused by our dependency on fossil fuels.
