She told me she ____ this day.a.won't never forgetb.will never forgetc.never forgot

To determine the correct option to fill in the blank in the sentence "She told me she ____ this day," we need to consider the tense and meaning conveyed by each option:

1. won't never forget: This option is grammatically incorrect due to the double negative ("won't" and "never"). This construction is typically considered incorrect in standard English.

2. will never forget: This option is grammatically correct. It indicates a future intention or promise and aligns with the context, as she is expressing a commitment to remember the day.

3. never forgot: This option is also grammatically correct but suggests that she did not remember the day in the past. This does not fit the context of the sentence where she is reflecting on her feelings about the day.

Final Answer

The correct choice is: b. will never forget.
