Official USCG Answer & Rule Citation

Correct Answer: Option D — All of the above

SOLAS regulations require ECDIS to maintain an independent, continuous voyage data recording log at one-minute intervals. This recording must capture ship position, course made good history, and official Electronic Navigational Chart sources for post-incident reconstruction.
