What do we learn from the passage about creativity? ( )

参考解析：

A项：in fact, it flourishes most fully when people are playful and childlike,并没有提到spiritually prepared（精神上准备好）.B项：It is a quality that is required by artists. But it is also present in the lives of scientists and entrepreneurs. 可知B表述错误。C项：it flourishes most fully when people are playful and childlike. At the same time, it works best in tandem with deep knowledge and expertise.文中只是提到创造力最好可以和深度知识和实践相结合，并没有提到它是由这两者创建的。D项：All of us benefit from it: we thrive mentally and spiritually when we are able to harness it. It is a delicate thing, easily stamped out 可知，创造力有利于智力的发展，但同时它也很脆弱。故本题正确答案选D。
