It requires understanding how the equilibrium temperatures of exoplanets relate to their orbital periods, factoring in their albedo. The task is to calculate the ratio of the orbital periods of ExoC to ExoA based on the given temperature ratios. The solution reveals that the orbital period of ExoC is approximately 25.9 times larger than that of ExoA."}
