A recent study found that cities with extensive bike lane networks

Question

A recent study found that cities with extensive bike lane networks tend to have lower levels of traffic congestion compared to cities with fewer bike lanes. Based on this, a city planner argues that expanding bike lanes in a congested city will necessarily lead to a significant reduction in traffic congestion.

Which of the following, if true, most seriously weakens the city planner’s argument?

(A) Many cities with extensive bike lane networks also have strong public transportation systems that contribute to reduced congestion.

(B) Expanding bike lanes requires reducing the number of lanes available for cars, which could initially increase congestion.

(C) A survey found that only a small percentage of residents in congested cities are willing to switch from cars to bicycles for their daily commute.

(D) In some cities, bike lanes are underutilized because of weather conditions and terrain, leading to no measurable impact on congestion.

(E) The cost of expanding bike lane networks varies widely depending on the city's existing infrastructure.

Can someone please explain to me how or why the answer is C?
A looks like the best answer as C is making an assumption that the congestion is caused by cars which the passage never mentioned.

I assume you chose  A . If you're wondering why  A  is incorrect, consider this: What if people show a strong preference for switching from cars rather than bikes? In that case, the number of cars would decrease, reducing congestion and freeing up road space. However, if people are not interested in switching from cars in the first place, the plan would fail. That's why the correct answer is  C

A.

"strong public transportation systems that contribute to reduced congestion." doesnt lead to the fact that extensive bike system doesnt reduce the traffic.
extensive bike system can still reduce the traffic and its fine if strong public transportation systems helps too.
