It is widely assumed that a museum is helped financially when a generous patron donates a potential exhibit. In truth, however, donated objects require storage space, which is not free, and routine conservation, which is rather expensive. Therefore, such gifts exacerbate rather than lighten the demands made on a museum’s financial resources.
Which of the following, if true, most seriously weakens the argument above?
(A) To keep patrons well disposed, a museum will find it advisable to put at least some donated objects on exhibit rather than merely in storage.
(B) The people who are most likely to donate valuable objects to a museum are also the people who are most likely to make cash gifts to it.
(C) A museum cannot save money by resorting to cheap storage under less than adequate conditions, because so doing would drive up the cost of conservation.
(D) Patrons expect a museum to keep donated objects in its possession rather than to raise cash by selling them.（E）
(E) Objects donated by a patron to a museum are often of such importance that the museum would be obliged to add them to its collection through purchase if necessary.

In B, two "most likely" possibilities does not remove the possibility that the one who donoates an exhibit WON'T donate cash.  Thus, the conclusion still holds.

B seems a reasonable choice for me too, could someone please enlighten me?

E says that the museum HAS to buy those exhibits anyway.  If the patron donates the exhibit, as least the museum saves the money for the purchase!

The conclusion depicts that donations would exacerbate rather than lighten the demands......

E. those donations are necessary to a museum, in other words, full fill the demands (weaken)
