Answer 1

The correct option is B increase in temperature

Carbon dioxide is main cause of green house effect. The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbondioxide, nitrous oxide, ozone, methane, for example) trap energy that comes from the sun.
Thus, increase of carbon dioxide gas in atmosphere will cause increase in temperature.
