由于疑惑，NN们帮忙！

　　4. Although it was once funded entirely by the government， the Victoria and Albert Museum was

　　one of the first of Britain's national museums seeking support from corporations and private

　　donors and to increase income by increasing attendance.

　　（A） one of the first of Britain's national museums seeking support from

　　（B） one of Britain's first national museums seeking support of

　　（C） among Britain's first national museums to seek support of

　　（D） among the first of Britain's national museums to seek support from

　　（E） among Britain's first national museums that have sought the support of

选D。

句子的后半部分是and to increase,所以前面要选to seek，所以排除A,B,E；从某处寻求支持，应该是用介词from。

另外，A选项连用两个of,显得awkawrd；BCE中的Britain's first national museums会引起歧义，句子的意思是最先寻求支持的博物馆之一，而不是寻求支持的最早建立的博物馆。
