$4.63 is to the whole cent. No rounding to nearest cent is possible.

Welcome! I'd call it a trick question.

I would not call it a trick question and I think rounding $4.63 to the nearest cent produces $4.63.
 
This is because Rounding is a function with a domain and a range.  When $4.63 is input, $4.63 is output.  It is simple, but not a trick.
 
Consider monthly interest on an interest-bearing checking account.  It is rounded to the nearest cent when posted to the monthly statement.  If the interest was $4.63 that month (that is high these days), then it would be rounded to $4.63 before posting to the account.

"Rounding" by its very definition demands the existence of something that can be rounded.
Consider "completing the square" of a perfect square trinomial. Impossible, it is already a "square."
