Answer:

In the sentence - For nearly two years after that, though, the Danes did not attack Alfred's native Wessex. At the end of 870 this changed, and this period as "Alfred's year of battles" from the excerpt taken from Alfred the Great - Part A by Lance Carson, “became known” should be used to fill up the blank. So, the right option is A.

Explanation:

The sentence from Alfred the Great is in past tense. The presence of “did not” in the  beginning of the sentence shows that it is in past tense. So, “became known” fits better with  this sentence and in completing the meaning of it. Also, this phrasal verb stands for getting  around or emerging which means something or some news getting spread across or  becoming aware among people. So, the use of “became known” completes the above sentence.
