Observe the pattern and choose the correct picture which should come next.

The answer is option 3. In the first pair of the images, the circle is inside the square and the outer part of the circle in purple color. In the second pair of the images, circle is inside the triangle and the outer part of the circle is pink color. So, the next image of the second pair will be the triangle inside the circle and the outer part of the triangle will be in pink color.
