Which adjective describes someone stubbornly refusing to change their mind?

• A. Obsequious
• B. Ostentatious
• C. Inexorable
• D. Obdurate

Answer: (D)

The main idea here is a person who refuses to change their mind despite reasons or arguments. Obdurate fits this idea exactly because it means stubbornly refusing to yield or be swayed.

Obdurate conveys a firm, perhaps even hard-hearted, stubbornness about one's position. It implies not just stubbornness in attitude but a kind of emotional rigidity.

Obsequious describes someone who is overly eager to please or serve others, not someone who resists changing their mind. Ostentatious means showy or flashy, which isn’t about stubbornness or opinion-change at all. Inexorable means relentless or unstoppable, often used for forces, events, or outcomes rather than a person’s unwillingness to change their mind, making it a less precise fit for this specific trait.

In a sentence: He remained obdurate in his stance, refusing to budge even after persuasive arguments.
