• A. So is my sister
• B. Her sister has either
• C. So has my sister
• D. Neither did mine

Answer 1

Answer: (C)

To express equal and same affirmative opinion about something, "so" is used in the answer which is in the same tense as the previous opinion. Hence, Option C is correct. The rest of the options do not adhere to this rule, hence incorrect.
