Graphs

Question

I think ans is option C , But will anybody explain the notation used in option D ?

Comments

question is incomplete without notation.Although $K$ is a famous notation for complete graoh.Assuming this

$K_4$ contains odd length cycle (size $3$),hence it can't be bipartite

Answer 1

If a graph is. Bipartite then chromatic number must be atmost  2.

 

Comments

Option a and d  are not define.

i assume k4 is complete graph and c4 is cyclic graph
