A park contains at most five of seven kinds of trees - firs, laurels, maples, oaks, pines, spruces, and yews - consistent with the following conditions:
If maples are in the park, yews are not. - Means Y are there or may be not, since M and S both are not in thepark.
If firs are in the park, pines are not. - Only F is there as ofnow.
If yews are not in the park, then either laurels or oaks, but not both are in the park. - This means Y are not there in the park either L or O are there. Thus, F and L or O are there for sure as of now. Two at least as ofnow.
If it is not the case that the park contains both laurels and oaks, then it contains firs and spruces. - Means either F is there or not since S is not there and it is the case that either L or O are there. Thus, F and L or O arethere.
If neither maples nor spruces are in the park, then which one of the following could be true?
(A) Exactly fourkinds of trees are in the park. - WRONG.
(B) Exactly[color=#e74c3c]
