For this question, refer to the diagram shown in Figure 2. This database is one that was used to collect data for an experiment. Participants were instructed to navigate multiple routes in a 3D virtual environment. The following information was collected: Participant details, including a unique ID, the experimental condition group they were assigned to, and whether they finished. Demographic questionnaire data for each participant (gender, age, etc.). Subjective experience questionnaire data for each participant to evaluate how they felt about the task they performed.

Navigation performance for each participant, for each route (i.e., completion time). Participants could only submit each questionnaire once. In terms of 1:1, 1:n, n:1, n:n, how is the participant table related to every other table?

(a) (1 point) How is participant related to log_navigation? (b) (1 point) How is participant related to questionnaire_TLX_STAI_map? (c) (1 point) How is participant related to questionnaire_demographics_general?
