Answer:

Option A: Increase in global temperature

Detailed Solution:

The correct answer is “Increase in global temperature”.

The Greenhouse Effect refers to the increase in global temperature.

This phenomenon occurs when certain gases in Earth's atmosphere, such as carbon dioxide, methane, and water vapor, trap heat from the Sun. This trapped heat leads to a warming of the Earth's surface, contributing to climate change and global warming.
