The term obdurate is best defined as

• A. Kind
• B. Cooperative
• C. Stubborn
• D. Flexible

Answer: (C)

This item tests your understanding of a word that describes someone who is stubborn and unyielding, resisting persuasion or change. Obdurate means unwilling to be moved by reasoning or appeals, often with a hard-hearted or inflexible stance. That makes “stubborn” the best fit, since it directly conveys a person’s persistent difficulty in changing their mind or actions.

The other options don’t match because they describe more positive or pliant traits: kind suggests warmth and consideration; cooperative implies a willingness to work with others; flexible means adaptable and able to adjust. None of these capture the sense of rigid resistance implied by obdurate.
