B: ________.

• A. I do too.
• B. So do I.
• C. I have too.
• D. So have I.
• E. Neither have I.

Answer 1

The correct option is D So have I.

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 D is correct. The rest of the options do not adhere to this rule, hence incorrect.
