A patient with a tumor in the esophagus will receive experimental endoscope treatment. The
first procedure requires a thin wire loop with an electric current around the tumor. The second
procedure, cryospray ablation, uses extreme cold to freeze tumor tissue with liquid nitrogen
spray. The third procedure, radiofrequency ablation, uses high energy radio waves from an
electrode that generates heat to destroy esophageal tumors. The cryospray procedure
destroyed the tumor. The surgeon believes the electric current loop will destroy the tumor in the
esophagus represents a (an):

A hypothesis
B scientific theory
C conclusion
D scientific law
E model
