1.	How many unique colors will be required for vertex coloring of the following graph?(a) 2(b) 3(c) 4(d) 5I got this question during an interview.This key question is from Graph Coloring topic in section Graph Coloring of Data Structures & Algorithms II
Answer» Correct OPTION is (b) 3 The EXPLANATION is: The given graph will REQUIRE 3 unique colors because two diagonal VERTEX are connected to each other directly. So its chromatic NUMBER will be 3.
