Answer:
Option (c)
Step-by-step explanation:
From the diagram attached,
First circle has 4 points on its circumference. By joining these points we get a quadrilateral inside the circle.
Second circle has 3 on its circumference. By joining these points we get a triangle inscribed in the circle.
In 3rd circle points on the circumference have been reduced again to 2. By joining these points we get a straight line.
Following the same pattern in the 4th circle we will get a single point on the circumference of the circle.
Therefore, Option (c) will be the answer.
