The correct answer is A) Lower left corner. The revision date of a nautical chart is typically printed in the lower left corner of the chart, as this is a standard location for this type of information. This placement follows the conventions and regulations set forth by the National Oceanic and Atmospheric Administration (NOAA) and other governing bodies responsible for the production and distribution of nautical charts. The other options are incorrect because the revision date is not typically found in the top center of the chart (B), as part of the chart title (C), or in a random clear area around the neat line (D). These locations would not follow the established standards for displaying this critical information on a nautical chart.
