Consider the situation.

Scientists discovered a sedimentary layer of earth with high amounts of the element iridium. This layer was laid down about the time at which the dinosaurs went extinct. Iridium is rare in Earth’s rocks, but it is commonly found in meteorites. Scientists suggested that a large meteor impact caused a layer of dust to envelope Earth, which may have resulted in the extinction of the dinosaurs.
Which type of scientific reasoning is being described in the situation?
deductive reasoning
inductive reasoning
scientific rationalism
scientific empiricism

B?

I would agree. From Google:

Inductive and deductive reasoning both strive to construct a valid argument. ... Therefore, inductive reasoning moves from specific instances into a generalized conclusion, while deductive reasoning moves from generalized principles that are known to be true to a true and specific conclusion.
