The correct answer is: A.It causes climate change and increase in the global temperature.

Explanation:

The increase in greenhouse gases (such as carbon dioxide, methane, and nitrous oxide) is a significant issue because these gases trap heat in the Earth's atmosphere, leading to the greenhouse effect. This effect is causing the planet's average temperature to rise, which in turn is driving climate change.

Why the other options are incorrect:

B.It can lead to a major increase in Greenhouses: This is not accurate. Greenhouse gases are compounds that trap heat in the atmosphere, not physical greenhouses. The increase in greenhouse gases does not cause more actual greenhouses to be built, but rather causes environmental changes.

C.It leads to more factories: The increase in greenhouse gases is actually caused by ...
