The correct option is (b) During volcanic eruptions
The explanation is: Volcanic eruptions produce carbon dioxide. The gas is released either during eruptions or through underground magma. Carbon dioxide through underground magma is released through vents, porous rocks, etc. that feeds volcanic lakes. Due to the production of significant amounts of carbon dioxide, volcanoes also contribute to global warming.
