Water cycle is effected by pollution, whether it is water pollution or air pollution. Air is polluted by Suspended Particulate Matter and by different harmful gases like Sulphur dioxide etc. These gases react with water vapours in the sky, making the water in the clouds acidic. This acid falls as rain water causing acid rains. This acid falls in ponds, on land, in fields, causing harm to us and to the crops as well as to the fishes or creatures in water. When the water evaporates from ponds, rivers and oceans to make water vapour, the the water in these water bodies becomes more acidic, and again when acid rains occur, this acid again mixes with the water of the water bodies, which already has acid, causing the water to become more concentrated.
The correct answer is - C. Colombia.
Colombia has a long tradition in coca production and than illegal trade with cocaine and unfortunately this is what is the country's trademark. Unlike some of the South American countries where it is noticed a drop in coca production, Colombia is actually having an increase in production, and a very significant one, every year in the past 6 years there's more and more plantations with coca and there is more and more cocaine production that ends up illegally all over the world. This process is mainly sponsored and under the wings of the Colombian cartels.
