Final answer:
The part of a lab report identified by the student's question is 'b. conclusion,' which interprets the research results and summarizes findings. Therefore, the correct option is b. conclusion.
Step-by-step explanation:
The part of a typical lab report that is correctly identified in the question is b. conclusion. A typical lab report often includes a title, abstract, introduction, method or procedure, results, followed by discussion or conclusion. The conclusion section is where one interprets the results and presents the conclusions of the research. Other important components of a lab report may also include references or a bibliography, which list all the sources cited and additional relevant literature respectively.
