A. Arbitrariness.

Explanation:

When Western Fence Lizards express territorial claims, their bellies turn blue. This illustrates the design feature arbitrariness.

Arbitrariness is the characteristic of being "by circumstance, instinct, or inclination decided and not by need, intention, or theory." It is often used to refer to a decision taken with little or no specific requirements or constraints. Arbitrary choices are not necessarily the same as those taken at random.

The highest priority for those people is Survival.

• The people living in Africa are known to be one of the poorest people in the world. Their gross domestic product and standard of living is smaller compared to other continents such as Europe or Asia.

• Examples of countries in Equatorial Africa include Gabon, Guinea, etc.

• The highest priority for such people is survival as they daily seek ways on how they'll survive.

• When there are opportunities, they seek for ways to migrate to other parts of the world where they'll have a better standard of living.

• In conclusion, the highest priority for most of the people living in Equatorial Africa is "survival".
