Answer 1

A. Marks the beginning of King Arthur´s reign.

Step-by-step explanation:

Although I did not find the exact date of King Arthur´s reign is the one that most approximates to the date given.

The Romans invaded England in A.D. 43.

English history dated way back before A.D. 597.

Finally, Alfred the Great became King of Wessex in 871.

King Arthur was a legendary British leader who led the defense of Britain against Saxon invaders in the late 5th and early 6th centuries.
