Correct answer: A
Explanation:
Look at each row of the 3 × 3 grid.
The rule is: the picture in the middle cell is the object that appears in both the left cell and the right cell.
In the first row, the left cell has a sailboat and balloon, and the right cell has a balloon and rocket. The common object is the balloon, so the middle cell is a balloon.
In the second row, the left cell has a balloon and rocket, and the right cell has a sailboat and rocket. The common object is the rocket, so the middle cell is a rocket.
In the third row, the left cell has a sailboat and rocket, and the middle cell is a sailboat. So the missing right cell must also contain a sailboat, but not the rocket again.
The correct missing picture is a sailboat and balloon, which matches Option A.
