  1. Step 1: Two independent clauses joined by a conjunctive adverb ('consequently') must be separated by a semicolon or period, followed by a comma. Step 2. Sentence A uses a semicolon before 'consequently' and a comma after it, correctly avoiding a comma splice. Answer: The clinical trial demonstrated positive efficacy; consequently, the regulatory agency granted expedited approval.
