An astronomer wants to visualize the relative distances between planets in our solar system. a biologist wants to examine the branching of blood vessels within the body. a chemist wants to see the angles between bonds in a molecule. a geologist wants to view the layers of the earth from core to crust.

what is the best method that all of these different scientists could use to perform their investigations?

a. perform a field study
b. create a controlled laboratory experiment
c. build a model
d. all of these

C. build a model

Explanation:

Build a model is the correct method so as to perform the investigation as the model can be used to simulate the astronomical, biological, chemical and geological natural processes occurring in nature. The model can give an idea about the cause of a natural phenomena. It can be used to mention the distance between the two separate bodies, morphological features of body of living organisms, the angles between the bonds of the molecules, it can also be used to describe the layers of the earth from core to crust.
