Summary
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.
Strongly Supported Conclusions
Angiogenesis is necessary for the development of fat.

a
The cells in ██████ ███ ████ ███████ ██ █████████ ██ ███ █████ ████ ██ █████ █████ ██ ███ █████
This answer is unsupported. We don’t know anything about the structure of tumor cells, fat cells, or any other cells in the body.
b
Drugs that inhibit ████████████ █████ ████████ ██████ █████ ██████ ██ ████ ███████
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.
c
Fat tissue depends ██ ████████████ ██ █████ ██ █████
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.
d
Rodents with cancer ███ ████ ██████ ██ ██ █████ ████ ███████ ████████
This answer is unsupported. We don’t know anything about rodents with cancer, or about the distribution of obesity in rodents.
e
Drugs that inhibit ████████████ ████ ███████ ██████████ ██ █████ ██████████
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.
