The correct answer is "The photograph enhances the explanation of the updated chronometer". The ship that carried Charles Darwin on his voyage around the world in the HMS Beagle has a nautical chronometer made by Thomas Earnshaw (1749-1828). Earnshaw further simplified the process of marine chronometer production, making them available to the general public. Thomas Earnshaw's Marine Chronometer No.509 was manufactured around 1800 and served on a number of Royal Navy ships to determine the longitude of a spot.
D.The photograph enhances the explanation of the updated chronometer
