Let G = (V, E) be a directed graph where V is the set of vertices and E the set of edges. Then which one of the following graphs has the same strongly connected components as G?

• A. G1 = (V, E1) where E1 = {(u, v)|(u, v) ∉ E}
• B. G2 = (V, E2) where E2 = {(u, v)|(v, u) ∈ E}
• C. G3 = (V, E3) where E3 = {(u, v)| there is a path of length ≤ 2 from u to v in E}
• D. G4 = (V4, E) where V4 is the set of vertices in G which are not isolated
