Choose the most appropriate ANTONYM of the given word.

Confident

diffident

The correct answer is option 3. diffident.

"Confident" describes someone who is self-assured, believes in their abilities, and feels secure in themselves. They are typically assertive and willing to take on challenges without fear or hesitation.

On the other hand, "diffident" is the opposite of confident. Someone who is diffident lacks confidence in themselves and their abilities. They may be shy, hesitant, or unsure of themselves, often feeling timid or lacking in self-assurance.

So, in the context of antonyms, "diffident" is the appropriate choice to contrast with "confident" because it represents the opposite characteristic.
