Within a city, consider 3 districts A, B, and C, each with n houses. Each house iscontained in exactly 1 district (i.e. there is no overlap between districts). Construct a networkof roads as follows:• There is a road between every house in A and every house in B.• There is a road between every house in B and every house in C.• There is a road between every house in C and every house in A.• There are no other roads except those specified above.(a) Express the number of roads in the city, in terms of n. Justify your answer.(b) Prove that you can walk to any house from any other house through some sequence ofroads.(c) Express the length of the longest cycle of roads in the city in terms of n. Justify youranswer.

Let us consider the houses as the nodes and the roads as the edges of the graph. Then, the…
