Detailed Answer Explanation

This question tests your understanding of sentence boundaries and punctuation. 'Either...or' is a correlative conjunction pair. No comma before 'or.' 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:

• "either...or (correlative)"

• "no comma in pair"

Why others are wrong: B (Semicolon is incorrect in correlative construction.), C (Colon is incorrect in correlative construction.), D (Comma is incorrect in 'either...or' construction.).
