A Tumor Is Actively Producing Both VEGF and FGF, Factors

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

A) Angiogenesis inhibitors are in greater concentration.
B) The tumor is metastatic.
C) Angiostatin is not produced by the cancer cells.
D) The VEGF and FGF are not functional.
E) Only one of the molecules is active, not both.
