Which of the following contributed most to the isolation of individual Greek city-states?

B. deep rivers
C. wide canyons
D. great lakes

The correct answer is A. Steep mountains contributed most to the isolation of individual Greek city-states.

Explanation:

Greece is a mountainous country located in southeastern Europe, on the southern part of the Balkan Peninsula and the surrounding Mediterranean islands. There are about 2,000 islands in Greece.

Greece is a mountainous country, with about 80% of its area composed by mountains of different altitudes. In the center of the peninsula, the Pindus mountains extend from north-west to south-east, and rise to 2637 meters high. The highest mountain of Greece is Mount Olympus, 2919 meters high.

These geographical characteristics contributed to the isolationism of the different Greek city-states, which were unable to establish a political continuity that would unify them into one nation.
