Correct option is B
Thermal pollution, which refers to an increase in water temperature due to industrial discharges or other anthropogenic factors, has the following effects:
· (B) Promotes the growth of certain fish: Warm temperatures may favor species adapted to higher temperatures, such as certain invasive or thermophilic species.
· (C) Increases the metabolism of fish: Higher temperatures accelerate metabolic rates, often leading to increased oxygen demand.
· (D) May cause elimination of most sponges and mollusks: Many aquatic organisms, such as sponges and mollusks, are sensitive to temperature changes and may not survive in warmer waters.
Incorrect Statements:
· (A) Increases the solubility of oxygen: Warmer water decreases the solubility of oxygen, reducing its availability.
· (E) Does not change the ecological balance of river: Incorrect, as thermal pollution disrupts ecological balance by altering species composition and oxygen levels.
