I'm not sure if you're really meaning to ask about question 9, because this question is about what tasks F, G, and L do, not what order they go in (you seemed to be analyzing different possible orderings of them).
The answer here is (A) because rule 3 says that G can't do harvesting. Rule 4 says that L can't do harvesting.
So that leaves F. He's the only one who can do harvesting.
Hope this helps.
