Choose the sentence that correctly uses a semicolon.

✓ Correct Answer: Option B

A semicolon correctly joins two independent clauses connected by a conjunctive adverb like 'however'. Option A is a comma splice. Option C incorrectly uses a semicolon to introduce a list. Option D uses 'then' as an adverb, not requiring a semicolon between independent clauses unless a conjunctive adverb is present.
