I think this question feels tricky because most people instinctively follow the causal chain: parking lot closed → need to find parking (takes time) → late. When you focus only on that chain, it’s easy to overlook the conditional.

Condition: If the maintenance had been on a different day, I would have arrived on time.

Rephrased: If there had NOT been maintenance today → I would have been on time. In other words: NO MAINTENANCE (PARKING OPEN) → ON TIME.

Once it is framed this way, answer choice C becomes the strongest match. It says that when the parking area in front of the building is open, the parking patterns in the area are normal and people arrive on time. The “when” introduces the conditional trigger. So if open parking triggers timely arrival, that directly supports the businessperson’s claim.

@Kevin_Lin Hello Kevin, Yes, I created those illustrations using AI. I usually learn how to phrase prompts to visualize cases/legal scenario illustrations to explain to my team/other staff. I really enjoy the process — as a visual learner, I find it incredibly helpful :)

Also just came back and noticed that the context sentence starts with "It is a given that" meaning something is considered an obvious, established, or guaranteed fact that requires no further proof or discussion. "It is a given that" is like "It goes without saying"... to indicate it's NOT the conclusion.
