Hi,
The correct answer option is {A}
Explanation
River Yangtze of China has cities lined up along its banks.This means that waste water and other solid waste matter from the cities could be deposited into the river causing water pollution.The industries along the river might release warm water and untreated waste water including harmful chemicals into the river increasing the pollution.In such a case, aquatic life will be at risk and some rare species of fish could die and completely become extinct.
