The answer is indeed letter D. an appearance by Halley's Comet.

Explanation:

The Bayeux Tapestry is a 230-feet-long strip of embroidered linen which depicts the Norman takeover of England. It holds great historical importance, and many historians use it as reference on medieval life, clothing, architecture, armory and so on.

Among the many scenes embroidered in it, the tapestry shows an appearance by Halley's Comet. As we know, Halley's Comet is a rare occurrence; it is only visible from Earth every 75-76 years. In the embroidered scene, the comet is depicted right after Harold's coronation, which is actually out of the proper chronological sequence. The comet appeared, in reality, more than 4 months after the coronation, but the scene was included there to display divine judgment for Harold's perjury.
