The correct answer is option B, Demos, Kratos.

Explanation:
Democracy is a form of government in which power is vested in the people. It is derived from two Greek terms: Demos and Kratos. Let's understand the meaning of these terms:

1. Demos:
Demos means "the people" or "the citizens" in Greek. It refers to the collective body of individuals who constitute a society or a community. In the context of democracy, it represents the idea that the ultimate power and authority should rest with the people.

2. Kratos:
Kratos means "rule" or "power" in Greek. It signifies the exercise of authority or governance. In the context of democracy, it symbolizes the principle of self-rule or the power of the people to govern themselves.

Combining the two terms, "Demos" and "Kratos," we get the word "Democracy," which literally means "rule by the people" or "government by the people."

Democracy as a Concept:
Democracy is not just a word but a concept that embodies the principles of popular sovereignty, equality, and participation. It is a system of government where decisions are made collectively and reflect the will of the majority. In a democratic society, citizens have the right to express their opinions, elect their representatives, and participate in the decision-making process.

Democracy in Practice:
Democracy can take various forms, such as direct democracy, representative democracy, or constitutional democracy. It has been practiced in different ways throughout history and across different countries. However, the core idea remains the same - the power lies with the people.

Conclusion:
The word "democracy" is derived from the Greek terms "Demos" and "Kratos," which mean "the people" and "rule" respectively. It represents the concept of self-governance and the idea that power should ultimately rest with the citizens. Democracy is a fundamental principle of many modern societies and is based on the values of popular sovereignty, equality, and participation.
