Correct Answer: Defeat

Solution : The correct choice is the first option.

Triumph represents a victory or success, while defeat represents a loss or failure.

The meanings of the other options are as follows:

• Capture implies seizing or taking control, which is different from the meaning of "triumph."

• While attainment implies reaching a goal, it doesn't convey the opposite of triumph.

• Succeed is a verb that means to achieve success.
