When would the No Action option be assigned to a hash in IOC Management?

The No Action option can be assigned to a hash in IOC Management when you want to save the indicator for later action, but do not want to block or allow it at this time. This option will neither detect nor prevent the execution of the hash, but will keep it in the IOC list for future reference. The other options are either incorrect or not related to the No Action option. Reference: CrowdStrike Falcon User Guide, page 44.
