Concept:Separation of power becomes meaningful when linked to checks and balances because it prevents the concentration of authority in any single branch of government.
Explanation:The doctrine of separation of power divides government into three main arms: the executive, the legislature, and the judiciary.
Each arm is given distinct functions to avoid an autocratic or dictatorial rule.
However, this separation alone does not guarantee good governance unless the arms are interconnected through checks and balances.
Checks and balances empower each branch to monitor and limit the powers of the others.
For example, the legislature makes laws, the executive implements them, and the judiciary interprets them and can declare any law void if it violates the constitution.
This system of mutual oversight ensures that no single branch becomes too powerful or abuses its authority.
Therefore, separation of power is given practical meaning and effectiveness only when it works together with checks and balances.
Answer:B. checks and balances
