Which characteristic should describe all evidence collected by a scientist? A. true
B. obvious
C. objective
D. subjective

Option C

Objective

Explanation:

When dealing with the study of natural phenomena, a purely objective approach must be made by scientists. This is because natural phenomena exist, devoid of human feelings or emotions. There is no room for subjectivity as the natural occurrences do not vary based on human thoughts and perceptions; rather they exist on their own.

Therefore, every evidence collected by scientists should be objective and analysis should be made based on characteristics displayed and not from their previous experiences or personal point of view.
