Below is a debate between scientists, after discovering and examining a fossil.

Marley: I believe that the bone is from a dinosaur
that flew because it is hollow

Evelyn: I disagree. The bone is hollow due to the
bone decomposing.

Manson: I partially agree with Marley. I believe that
the bone is hollow because it is from an
ancient bird.

Sheldon: Perhaps the bone is hollow because
other organisms ate it.

What steps would a scientist mostly likely take following this debate to determine a scientific
conclusion?

A. Compare the dinosaur fossil to dinosaur bones discovered by other scientists at a museum.
B. Share their findings in order to compare them with accepted findings from the scientific community.
C. Reading a paper published by a professor at a university and base all further decisions on the evidence found in that paper.
D. Pick an expert on fossils from the scientific community to conduct a study and decide which scientist came up with the best hypothesis about the fossil.
