Select the most appropriate ANTONYM of the given word.

Flexible

Defiant

The correct answer is option 2. Defiant.

"Flexible" describes something or someone that is adaptable, easily bent, or capable of bending without breaking. It implies a willingness to change or compromise.

On the other hand, "defiant" describes something or someone that openly resists or challenges authority or rules, showing a refusal to obey. It implies a stubborn or rebellious attitude.

Therefore, "defiant" is the most appropriate antonym for "flexible" because it represents the opposite quality of being unwilling to adapt or compromise, instead showing resistance or disobedience.
