In this case, we must consider that a factor is a cause, so we need to identify those events that are a cause. Now climate change refers to a long-term change in temperatures, this can be due to natural causes or human actions. Taking this into consideration we can say that solar energy generates an increase in earth's temperature, without it, life on earth wouldn't be possible also volcanic eruptions play an important role if the release of greenhouse gases is massive can lead to an increase in global temperature, therefore we can say that the correct answers are options 3 and 4.
