D. The daily release of hot water into the pond from a local factory.
Explanation:
The daily release of hot water into the pond from a local factory would most likely affect the health of fish in a local pond.
Fishes are cold blooded animals. They derive their temperature from the water around them. They need a fairly stable daily temperature.
If the temperature of the water varies to a large extent too much daily, they will suffer.
Hot water will affect the fish population badly. It will cause the fishes to die off and suffer from too much increase in temperature.
Other factors listed in the options will improve the fish life.
