Solution

The correct option is D Both (A) and (C)
The melting of the polar ice caps is caused by the overall increase in global temperature, and this melting can have serious consequences for all organisms on Earth. Besides being important for marine life, ice caps help regulate sea level and global temperatures.
Not only does the melting of the ice caps increase the volume of water in the oceans, it also decreases the salinity, or salt content.
Polar ice caps are made of fresh water, so adding more fresh water without adding more salt makes the ocean water less saline. This can cause problems for organisms that are well adapted to the very salty ocean waters.

Global warming is a gradual increase in the average temperature of the earth’s lower atmosphere as a result of the increase in greenhouse gasses since the Industrial Revolution. Much of the recent observed and projected global warming is human-induced. It is caused by man-made increases in carbon dioxide and other greenhouse gasses through the burning of fossil fuels and deforestation. Adding carbon dioxide, methane and such other gasses (that have the potential to absorb heat) to the atmosphere with no other changes will make our planet’s surface warmer. The atmospheric concentrations of carbon dioxide and CH4 have increased by 31 per cent and 149 per cent respectively above pre-industrial levels since 1750.
