Why

“My bad” is a casual admission that the mistake was the speaker’s. The promised correction also shows responsibility; the phrase alone would be too casual for a serious error.

✕ Not quite

Why

The third option confirms the exact commitment in a professional register. The first two are natural ways to show interest in a casual plan, but they are too informal and less precise for this deadline.
