Explanation:

A central idea (or main idea) of a text can be a specific topic with details (like a non - abstract, topic - based statement) or a general theme. The options "Kindness is its own reward", "Friendship is important", and "It’s better to give than receive" are more like general themes or universal ideas. "Pollution in the ocean is harming marine animals" is a specific statement about a topic (ocean pollution and its effect on marine animals), which can serve as a central idea for a text focused on that specific issue.

Answer:

B. Pollution in the ocean is harming marine animals.
