Correct answer: B
Explanation
The correct answer is option 2, i.e., live.
The sentence is referring to dolphins that exist or reside in freshwater. The verb needed here should indicate where they dwell or stay.
Live – correct verb form meaning “reside in”; fits the sentence contextually and grammatically.
Exits – incorrect; means “leaves” or “ways out.”
Settle – implies establishing permanently, which is not the intended meaning.
Life – noun; doesn’t fit grammatically.
Final Sentence: There are very rare and few dolphins in the world that live in fresh water, rivers, and lakes.
