Answer: Option (B) is the correct answer.
Explanation:
When people catch fish or other sea food in order to commercially sell them then this kind of activity is known as commercial fishing.
So, people who earn their livelihood by selling fishes or other sea food animals have to go under water in adverse conditions and thus, they put their life at risk just to earn their bread.
This leads to an increase in human fatalities.
Thus, we can conclude that an increase in human fatalities is a negative consequence of commercial fishing.
