Answer:
E
Step-by-step explanation:
1. The series seems to alternate between adding one letter and then skipping one letter.
2. The first letter is B, then it skips A and adds C.
3. Following this pattern, after C (the last added letter), we should skip one letter (D) and add the next letter (E).
4. Therefore, the next letter in the series after D F would be E.
