In 2001, scientists announced that they had discovered a species of dinosaur called albertaceratops nesmoi that they believed to be an ancestor of another better-known dinosaur species. how would scientists have determined that this newly discovered species was related to other known species of dinosaur?

This question had choices. These are the missing choices.
A)Scientists made careful observations of behavioral patterns.
B)The DNA mutation rates for both species was calculated and compared.
C)Scientists made a detailed analysis of the fossilized bones of each species.
D)The enzyme activity of each species was studied to determine similarities in metabolism.

My
C)Scientists made a detailed analysis of the fossilized bones of each species.

This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
