A. morning is✓ Correct

D. morning; is

Detailed Answer Explanation

This question tests your understanding of sentence boundaries and punctuation. 'Running every morning' is a gerund phrase acting as the subject. No punctuation separates subject from verb. To determine the correct answer, examine where complete thoughts begin and end. Look for independent clauses that need proper separation. A period, semicolon, or appropriate conjunction can correctly join or separate these ideas. When analyzing sentence boundaries, pay attention to how ideas flow from one sentence to the next. Correct punctuation ensures clarity and prevents confusion for readers. Review the options carefully to identify which choice creates proper sentence structure.

Key Evidence:

• "gerund phrase as subject"

• "subject-verb connection"

Why others are wrong: D (Semicolon incorrectly separates subject from verb.), C (Comma incorrectly separates subject from verb.), B (Colon incorrectly separates subject from verb.).
