Correct Answer: Thermal pollution
Solution : The correct answer is thermal pollution.
Thermal pollution happens when untreated hot waste water from industries is directly released into the water body and it increases the ambient temperature of water. It is harmful for marine life and organisms which have low tolerance to the fluctuating temperatures as they don't exhibit the property of thermoregulation. Hot waters have low oxygen concentration which affects the marine life negatively.
