Hello. You did not provide answer options. This prevents your question from being answered 100% satisfactorily. However I can help by showing the meaning of the verb "to harrow" and showing examples of phrases that were spelled correctly.
The verb "to harrow" can have two meanings, the first refers to the act of preparing the soil for the cultivation of plants through equipment called harrow, which leaves the soil smooth and free of clods. In this case, an example of a phrase that would use this verb correctly would be: We cannot plant corn without harrowing the land first.
The verb "to harrow" can also be used in the sense of causing torment to something or someone. In this case, an example of a phrase once this verb is used correctly is: "has not set out to appall the reader with horrors nor to harrow him with miseries."
You know it's a definition because it provides the meaning of the word inside commas directly after the word. It's not a synonym nor an antonym because it's not one word, and it's not an inference because you're not making an educated guess about the word based on the rest of the sentence. The sentence is <em>directly</em> telling you what the unknown word means, so it must be a definition.
