Let's break this down.

The sentence describes Oscar Wilde's witty reply to customs: "The only thing I have to declare is my genius."

This shows clever, playful, mischievous wit - not just arrogance, but a humorous, sharp, selfaware kind of cleverness.
- A. arch - yes, means "knowingly clever or mischievous" - fits Wilde's wit.
- B. narcissistic - means self-obsessed; while his reply is self-praising, the tone is more playful than purely narcissistic.
- C. successful - not relevant to the quote.
- D. misanthropic - means hating humankind - not supported.
- E. puckish - yes, means playful, mischievous - fits perfectly.
- F. accomplished - not directly supported by the quote.

The best two are A. arch and E. puckish - both capture the clever, mischievous wit.
