The correct answer is B. The sentence is redundant; it unnecessarily repeats the same concept.
Explanation:
A sentence is redundant when information is repeated, this often means there is an excess of words and therefore some of these words can be deleted without affecting the original meaning. In language, redundancy should be avoided because it might distract or confuse the audience. In the sentence presented the problem is redundancy because the sections "every Friday" and "weekly" mean the same and thus, there is unnecessary repetition of the same idea (option B).
