Despite looking for her . . . . . . . ., I couldn’t find her. A. somewhere B. anywhere C. everywhere D. nowhere

The correct answer is D. nowhere.

The other options are not correct because they do not convey the sense of not being able to find someone.

• Somewhere means in one or more places.
• Anywhere means in any place.
• Everywhere means in all places.

The sentence “Despite looking for her everywhere, I couldn’t find her” means that the speaker looked for the person in all places, but they were not able to find them. This is consistent with the meaning of the word “nowhere,” which means in no place.
