What will be the chromatic number of the following graph?(a) 2(b) 3(c)

1.	What will be the chromatic number of the following graph?(a) 2(b) 3(c) 4(d) 5I have been asked this question by my school principal while I was bunking the class.The doubt is from Graph Coloring topic in division Graph Coloring of Data Structures & Algorithms II
Answer» RIGHT answer is (b) 3 The best EXPLANATION: The given graph will require 3 unique colors so that no TWO vertices connected by a common edge will have the same COLOR. So its chromatic number will be 3.
