Correct Answer: conceited

Solution : The correct choice is the third option.

Modest implies humility, not drawing attention to oneself, and being unassuming or not boastful, whereas conceited means having an excessively high opinion of oneself and often involves showing off or being self-centred, which makes it the correct antonym for modest.

The meanings of the other options are as follows:

• Distant means farther away in space and time and doesn't directly relate to the concept of "modesty".
• Unpresuming means humble and is a synonym for "modest".
• Obvious means clear and easily perceived.
