What does "plutocracy" refer to?

"Plutocracy" specifically refers to a political system in which power is held by the wealthy. The term is derived from the Greek words "ploutos," meaning wealth, and "kratos," meaning power or rule. In a plutocracy, those with significant financial resources have substantial influence over political decisions, often leading to policies that favor their interests.

The other choices present different concepts that do not align with the definition of plutocracy. A mixture of liquids pertains to chemistry or mixtures, while a stubbornly unyielding attitude refers to inflexibility or obstinacy, which has no connection to wealth or governance. Lack of respect addresses issues of civility and regard but does not relate to a political framework influenced by wealth. Therefore, the correct answer effectively captures the essence of the term "plutocracy."
