Correct Answer: Irresolution

Solution : The correct choice is the first option.

Perseverance refers to the quality of persisting and continuing with determination despite difficulties or obstacles.

Irresolution, on the other hand, means a lack of decisiveness or determination, which is the opposite of perseverance.

The meanings of the other options are as follows:

• Obstinacy: Obstinacy is related to stubbornness and persistence in one's own ideas or actions, which is not necessarily the opposite of perseverance.
• Readiness: Readiness means being prepared or willing to do something, but it is not necessarily an antonym of perseverance.
• Eloquence: Eloquence refers to the ability to speak or write fluently and persuasively, which is not directly related to the concept of perseverance.

Therefore, the correct antonym is "irresolution."
