A check that is still valid for cashing or depositing is referred to as a valid check. This means that the check has not been altered, stopped, or marked as non-negotiable by the issuer, and it still contains sufficient funds in the account to be cashed or deposited. A valid check can be presented to a bank for processing, and there are no restrictions preventing the bank from honoring it.

In contrast, a dishonored check refers to one that the bank has refused to pay due to insufficient funds or some other issue. A postdated check is written with a future date and cannot be cashed or deposited until that date. A canceled check is one that has been paid and marked as such, no longer usable for cashing or deposit. Therefore, a valid check signifies that it remains active for transactions, confirming it as the correct answer to the question.
