The Authority of Heads of State and Government occupies the highest position within the ECOWAS structure.
It formulates major policies, sets overall objectives, and provides direction for all ECOWAS institutions.
Because it consists of national leaders, its decisions carry the highest level of legitimacy and binding force within the organisation.

Redistribution of income involves government policies that directly influence how income is shared within the economy.
Market intervention, transfer payments, and taxation are active tools used for redistribution.
Limited liability, however, is a legal principle protecting owners from excessive losses; it does not function as an income redistribution mechanism.

The principle of certainty states that taxpayers must clearly know what they are to pay, when to pay, and how payment is to be made.
This eliminates confusion, reduces arbitrary assessments, and promotes transparency in a tax system.

Money serves multiple functions including acting as a medium of exchange, a means of settling debts, and a medium of payment.
Since all the listed characteristics describe money, the most comprehensive answer is the option combining them.

Business cycles refer to fluctuations in economic activity over time, including phases such as expansion, peak, recession, and recovery.
Recession is a key component of the cycle as it represents the downward phase characterised by falling output and reduced economic activity.

Economic problems arise because resources are limited relative to the unlimited wants of society.
This scarcity forces individuals and governments to make choices on allocation, forming the basis of all economic decision-making.

When the value of the domestic currency falls relative to a foreign currency, it loses purchasing power internationally.
This fall is known as depreciation, meaning fewer units of foreign currency can now be bought with the domestic currency.

Economic growth depends on many factors, but human capital is the most critical because it drives productivity, innovation, and efficient resource use.
A better-educated and skilled workforce enhances long-term development more effectively than physical resources alone.

When income rises but prices remain unchanged, the consumer can afford more of all goods.
This expands purchasing power and causes the budget line to shift outward in a parallel direction, showing increased consumption possibilities.

The law of supply describes producers’ behaviour: firms are willing to supply more of a good at higher prices because higher prices raise potential profits.
This results in an increase in quantity supplied rather than supply itself.
