Some anticancer drugs work by depriving tumors of needed blood vessels. The drugs work by preventing angiogenesis, which is the creation of blood vessels. The same drugs have been discovered to prevent obesity in rodents.

Angiogenesis is necessary for the development of fat.

This answer is unsupported. We don’t know anything about the structure of tumor cells, fat cells, or any other cells in the body.

This answer is unsupported. The stimulus only says that the drugs have been found to prevent obesity in rodents. We don't know if that extends to humans, or to weight loss rather than preventing weight gain.

This answer is strongly supported. The drugs inhibit angiogenesis, so since the drugs prevent obesity in rodents, we can infer that inhibiting angiogenesis prevents obestity. In other words, fat cell growth requires angiogenesis.

This answer is unsupported. We don’t know anything about rodents with cancer, or about the distribution of obesity in rodents.

This answer is unsupported. We don’t know if the drugs have any other effects besides inhibiting angiogenesis. And the stimulus never suggests that the rodents mentioned have vital nutrient deficiencies.
