Question 14 Explanation:
A planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints.
In other words, it can be drawn in such a way that no edges cross each other.
Option-A is planar.
Option-B is planar
Option-C is non planar
In other words, it can be drawn in such a way that no edges cross each other.
Option-A is planar.
Option-B is planar
Option-C is non planar
Correct Answer: D
