Answer:
O A semicolon should precede the conjunctive adverb.
Step-by-step explanation:
However functions as a conjunctive adverb because it joins two independent or main clauses. Thus, it is not considered neither a coordinating nor a subordinating conjunction, even though it works similarly to coordinating conjunctions. As a result, the two independent or main clauses, which consist of two complete thoughts, must be separated by a semicolon before the conjunctive adverb.
