Given the following:

Vertex set: $V(H)=\{0,1,2,3,4,5,6\}$ for graph $H.$

Indicate which of the following edge sets $E(H)$ correctly represents the graph.

a$.E(H)=\{(6,4,2,0),(4,3,0),(0,1),(6,4,2),(4,3),(6,5,4),(6,5),(6,2)\}$

b$.E(H)=\{(1,0),(0,2),(2,6)\}$ or $E(H)=\{(1,0),(0,3),(3,4),(4,5),(5,6)\}$ or $E(H)=\{(1,0),(0,2),(2,4),(4,5),(5,6)\}$

c$.E(H)=\{(0,2),(0,3),(1,0),(2,4),(3,4),(4,5),(5,6),(2,6)\}$

d$.E(H)=\{(0,2,3),(1,0),(2,4,6),(3,4,5,6)\}$

Q$.$ Unable to determine the edge set, as the starting and end points do not connect.
