The correct answer is A. Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.
Explanation:
In the scientific method and science, the correct term to define the explanation proposed by a scientist about the phenomenon or event he wants to study is a hypothesis. On the other hand, the term theory in science is used to refer to explanations that have been repeatedly proved or confirmed. This implies the idea "cigarette smoke will influence web-building in spiders" in Robert's experiment is a hypothesis and not a theory and therefore, the statement "Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders" contains an incorrect use of a scientific term.
