Balkan Peninsula is a headland of Greece, Bulgaria, Yugoslavia, Romania, Albania and Hungary under Ottoman Turkish rule. It is a geographic area in a southeastern part of Europe. The country takes the name from Serbian-Bulgarian border to the Black Sea’s Balkan Mountains. The geography was rotating around its three characteristics: its mountains, its rivers, and its area’s situation. The Peninsula itself is a triangular shape with a broad northern borderline, straitening to a tip as it extends to the south surrounded by the Black, the Aegean, the Mediterranean and the Adriatic Seas; they served each other as barriers and access points. Balkan is different from other peninsulas, it is not being secluded from nearby regions. Most of the ethnic groups in the region were entering in the access points of Romania in the northeast, Ukraine in the steppe regions, Danube and Hungarian in the northwest. Balkan is surrounded by 3 sides of water; the neighboring regions to the east, west, or south, the narrow channels of Bosphorus and the Dardanellas which are the natural passage between Anatolia and Balkans, and beyond Asia. Balkan is unsurprisingly a region that has been intersections for traffic accessing to and from all these destinations.
You would definitely not expect political stability in a state that is being annexed or which does not have a territory - rather the opposite would be true.
Both multinational and souvereign states can have a high lever of political security. However, in a multinational state one can also expect some conflicts between the different ethnic groups - therefore the best answer is "a sovereign state"

Answer: D. both A and B
Explanation:
Earth is the only planet that is capable of supporting life as we know it due to the presence of temperature, oxygen, an atmosphere and energy.
All the above contribute in the following ways;
- Atmosphere - The atmosphere is sort of like a protective barrier around earth. It destroys a lot of foreign objects that fall on earth and traps the sun's rays such that we keep us adequately warm. It also contains both oxygen and carbon dioxide which living things rely on.
- Energy - The presence of energy sources on Earth enables us to be able to survive. Energy sources like fire, water, and solar enable us to do things such as cooking and electricity generation, that ensure our survival.
- Nutrients - The nutrients available on Earth ensure that living things can grow and survive.
- Temperature - A very important factor, Earth has the right amount of temperature necessary for the proliferation of life. It is not too cold that living things are unable to metabolize food and freeze and is not too hot that life cannot survive.
