请教GWD24的一道语法 seeming 和appearing

misslila

Appearing to be the only candidate whose views would beacceptable to its membership, the Youth Canorous finally endorsed George forcity council.
A.      Appearing to be
B.     Seemingto be
C.     Becausehe appeared to be
D.     Becausehe seemed
E.      Being


答案是c。看了解释之后明白了ABE的逻辑主语有问题。
但是还是想请教一下seem和appear有什么区别呢？
如果d改为he seemed to be对不对呢？
谢谢～～

seem和appear一个主动一个被动

一个是被别人看来是什么样的，一个是它自己展示给别人的是什么样的

因此改为seemed to be也改变了句子本来的意思。
