Chinese public education warmly reminds you to choose the fourth question.

The reason is the relationship between the third figure and the first two images.

That is to say, the first and second figures overlap, the overlapping is eliminated, and the non-overlapping is left, resulting in the third figure, so the answer is D.

Welcome students to visit the website of Chinese public education or the online school of Chinese public education.
