Correct Answer:
A. Extraordinary
The correct answer is Extraordinary because quotidian denotes things that are daily, mundane, or ordinary, which directly contrasts with something rare or remarkable.
- Extraordinary: This is the correct choice. 'Quotidian' originates from the Latin *quotidie* (meaning 'every day'). Since it describes routine, commonplace events, its precise semantic antonym is something that is out of the ordinary, rare, or exceptional.
- Incorrect Options:
- Wishful: This is incorrect. It describes having or expressing a desire for something to happen that is highly unrealistic.
- Premature: This is incorrect. It describes something occurring or done before the proper, expected time.
