Which part of a thesis is the bold area in the below example? isaac newton made a profound impact in the fields of science, math, and philosophy. a. topic b. position c. reasons/subtopics

This part of the thesis would be considered the topic, more specifically it would be considered the introduction of the topic to study since the thesis revolves around, I assume, Isaac Newton and you are offering a brief 'summary' of his life and accomplishments.

However if the reason to mention Sir Isaac Newton is to support an idea or a statement this could be considered a subtopic. It is subjective and directly related to the field of study you're doing the thesis for.

Hope this helps!
