Explanation:
The thesis statement or main claim is one of the most important elements in a research paper because this expresses the issue and the position about it the author is trying to prove through evidence. This thesis statement is created at the beginning of the writing process but can be changed if this is necessary. For example, the author might find out evidence does not support the initial thesis statement and will need to modify the thesis statement according to the evidence. Thus, it is false the thesis statement is final and should not be changed (Option C).
