To identify the correct punctuation, we need to understand the rules for punctuating coordinating conjunctions and transitions. In this case, the conjunction "however" is used to join two independent clauses, so a semicolon is needed before "however" and a comma is needed after "however" to separate the clauses. Correctly punctuating the sentence helps clarify the relationship between the two clauses and improves readability.
