1.	What will be the chromatic number of the following graph?(a) 2(b) 3(c) 4(d) 5I got this question in class test.My question is from Graph Coloring topic in division Graph Coloring of Data Structures & Algorithms II
Answer» The CORRECT answer is (b) 3 Easiest 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.
