- BThe NtM number, year, and date of correction✓ Correct
- COnly the date the correction was applied
- DThe USCG district that issued the local notice
Explanation
Standard practice is to note the NtM number and year (e.g., 'NtM 14/26') in the chart's correction record on the chart border or title block, along with the date applied. This allows any subsequent user to verify which corrections have been incorporated and identify the authoritative source.
