Review the section \"Investigating Life: Cutting off a Tumor\'s Supply Lines in the War on Cancer.\" Imagine that a mutation occurs during endothelial cell division that makes the daughter resistant to endostatin. Would natural selection favor this phenotype in the presence of endostatin? No. Endostatin does not affect endothelial cell reproduction, so natural selection has no effect on endothelial cells. No. Endostatin does not kill endothelial cells, so natural selection has no effect on endothelial cells. Yes. This cell and its progeny will divide more quickly than other endothelial cells. No. Endostatin targets cancer cells, not endothelial cells. Yes. This cell and its progeny will not be killed, unlike other endothelial cells.

Solution

Yes. The natural selection would favor this type of phenotype in the presence of endostatin as it is providing survival to the mutant daughter cells. Hence the last option would be correct.
