Medical Researchers Are Excited About a New Cancer Treatment That

Medical researchers are excited about a new cancer treatment that destroys tumors by cutting off their blood supply. To date, the treatment has only been used on mice, but in mice it has been nearly 100% effective in eradicating tumors and appears to have no side effects. As evidence of the effectiveness of the new treatment in treating cancer in humans, these studies:

A) display a high degree of statistical significance, and so the treatment will work in humans with nearly 100% certainty.
B) are convincing, assuming the results have been replicated in a large number of mice.
C) are convincing, assuming that proper randomization and control were used.
D) suffer from lack of realism.
