[单选题]If there exists a polyhedron with cameras located in each vertex, some inner area of the polyhedron still can't be viewed. It means that
我们说三维空间中的一个多面体，如果多面体每个顶点放置一个摄像头，仍然无法覆盖所有内部区域，其实是说？
AThere are few vertices of the polygon (意味着这个多面体的顶点数很少)
BThere are a lot of vertices of the polygon (意味着这个多面体的顶点数很多)
CThere is a point inside the polyhedron which connect each vertex crossing the faces of the polyhedron (意味着多面体内存在一个点，与所有顶点连线皆穿过多边形的面)
DThere is a point inside the polyhedron which connect some vertex crossing the faces of the polyhedron (意味着多面体内存在一个点，并存在与之相连会穿过多边形的面的顶点)
