A tumor is actively producing both VEGF and FGF, factors associated with angiogenesis.  However, no network of blood vessels to the tumor has been established in spite of the fact that blood vessels are nearby.  This observation most likely suggests that
A) the VEGF and FGF are not functional. 
B) angiogenesis inhibitors are in greater concentration. 
C) only one of the molecules is active, not both. 
D) angiostatin is not produced by the cancer cells. 
E) the tumor is metastatic.
