Previous studies have suggested that volcanic eruption will release a lot of heat and cause global warming, but recent studies have found that volcanic eruption not only does not cause global temperature rise, but can also weaken the impact of global warming. Which of the following is true and best supports the above conclusion? ['Studies have shown that underground magma ejected from the ground during a volcanic eruption, resulting in an oxidation reaction in contact with air, causing local temperature rise.', 'A volcanic eruption can inhibit certain bacteria that decompose organic matter. The decomposed organic matter contains methane, which is a flammable gas and can generate heat.', 'Large-scale acid rain will be brought after the volcanic eruption. Acid rain can reduce the temperature of the volcanic area in the short term, but it also causes pests of crops.', 'Studies have found that volcanic eruption substances-sulfur dioxide can form "water particles" with atmospheric substances and reflect sunlight, reduce heat radiation to the ground, and delay global warming.']
