Q. Which complete graph is not present in minor of Outer Planar Graph?

  • (A) k3, 3
  • (B) k3, 1
  • (C) k3, 2
  • (D) k1, 1
πŸ’¬ Discuss
βœ… Correct Answer: (C) k3, 2
Explanation: minor graph is formed by deleting certain number of edges from a graph or by deleting certain number off vertices from a graph. hence outer planar graph cannot contain k3, 2 as a minor graph.
