G X S N F L T N G Z F B J M J Z B F Q C X S P M J

Correct option is A

Given String:
G X S N F L T N G Z F B J M J Z B F Q C X S P M J
Solution:
Let's go through each letter and check if it is immediately followed by either B or F.
1. N F — The letter N is followed by F (count = 1).
2. Z F — The letter Z is followed by F (count = 2).
3. F B — The letter F is followed by B (count = 3).
4. Z B — The letter Z is followed by B (count = 4).
5. B F — The letter B is followed by F (count = 5).
Final Count:
There are 5 instances where a letter is immediately followed by either B or F.
Answer:
