What is the effect of this declaration?

I answered : A & C
The book says : C & D

Why it should not be D : Because it is restricting PUT and DELETE for specific resources with the file path in it and not ALL Resources.

Or is the language used ambigious???

It's a subtle point in the language: option A says that this constraint prevents any PUT or DELETE operations from occuring [end of statement]. However, this isn't true, because any user authenticated under the 'admin' role can use PUT and DELETE operations and they will be successful (this is the correct option D). So A is incorrect because it doesn't stop any PUT or DELETE, only those where the user is not in the 'admin' role. Option D is the correct alternative.

I admit the question could have been slightly better phrased, but the answer made it clear to me what was/wasn't true when I re-read it.
Consider Paul's rocket mass heater.
