The statement that accurately compares the government systems of Sparta and Carthage is:
The Spartan and Carthaginian governments both had two leaders. The Spartan government had hereditary kings while the Carthaginian government had elected leaders.
This reflects the dual kingship in Sparta, where two kings ruled simultaneously, and the elected leadership in Carthage, where officials were chosen through elections.
The other statements contain inaccuracies about the nature of the assemblies, councils, and the emphasis on military matters versus democratic features. Specifically, Sparta was more oligarchic rather than democratic, and while both had councils, the descriptions of the number of officials are incorrect.
