Which word encapsulates the idea of "imperious"?

The word "imperious" conveys a sense of commanding authority and superiority that often comes across as arrogant or domineering. It describes someone who behaves in a way that suggests they are superior to others, expecting obedience or compliance without question. This aligns perfectly with the idea of "having or showing arrogant superiority," as both concepts emphasize a sense of entitlement and a lack of regard for others' perspectives or feelings.

The other choices, while they may involve various qualities or traits, do not capture the essence of "imperious." A natural inclination, official approval, and stubbornness each refer to different characteristics that do not relate to the commanding or superiority aspect inherent in "imperious." Therefore, the correct choice highlights the appropriate meaning and sentiment associated with the term.
