Answer:
A) It has excessive coordination.
Explanation:
Coordination refers to the organization of the different elements of a sentence, which makes them work together effectively or go together well.
The sentence given contains four independent clauses which do not work well together. Independent clauses must be separated from one another by a colon, semicolon, or a comma plus a coordinating conjunction. Therefore, a revision of the sentence would include their separation with a semicolon:
<em>Matt Sorum was playing with The Cult and he was recruited by Slash of Guns and Roses</em><em>; </em><em>so he played with Guns and Roses, but he has since returned to The Cult.</em>
