Final answer:
A post-dated check is a check written with a future date; it is not negotiable until that specified date, but can be converted into cash or another negotiable instrument afterwards.
Step-by-step explanation:
The correct answer to your question is A) Post-dated check. A post-dated check is a check that is written with a date that is in the future, which means it is not negotiable until that date arrives. It cannot be cashed or deposited until the date indicated on the check. While the check itself is not immediately negotiable, it is understood that it will become so once the indicated date has passed, at which point it can be converted into cash or a negotiable instrument.
On the other hand, a bank draft is a check drawn by a bank against funds deposited into its account from the purchaser, a conditional check is one that is subject to a condition being fulfilled, and a blank endorsement refers to the signature of the payee on the back of a negotiable instrument, which then allows it to be transferred to another party.
