Answer is Wrong!
Answer is Right!
The correct answer is C. expiration date.
An expiration date is the last day on which an option can be exercised. For European options, this is the only day on which they can be exercised. For American options, they can be exercised on any day up to and including the expiration date.
A European date is the date on which a European option expires. An American date is the date on which an American option expires. A money date is not a term used in options trading.
